General Description
The AAT3113/13A and AAT3114/14A are low noise,
constant frequency charge pump DC/DC converters
that use fractional (1.5X) conversion to increase effi-
ciency in white LED applications. The devices can
be used to produce current levels up to 20mA for
each output from a 2.7V to 5.5V input. A low exter-
nal parts count (two 1F flying capacitors and two
small bypass capacitors at V
IN
and OUT) makes
these devices ideally suited for small battery-pow-
ered applications.
AnalogicTech's Simple Serial ControlTM (S
2
CwireTM)
interface is used to enable, disable, and set the
LED drive current for 32-level logarithmic scale LED
brightness control. AAT3113/13A and AAT3114/14A
devices have a thermal management system for
protection in the event of a short-circuit condition on
any of the output pins. Built-in soft-start circuitry
prevents excessive inrush current during start-up.
A high switching frequency enables the use of small
external capacitors. A low-current shutdown feature
disconnects the load from V
IN
and reduces quies-
cent current to less than 1A. The AAT3113/13A
provides four LED current source outputs, and the
AAT3114/14A provides six. The AAT3113/13A is
available in the Pb-free 12-pin TSOPJW package,
and the AAT3114/14A is available in the Pb-free 16-
pin QFN package.

Functional Description
The AAT3113/13A and AAT3114/14A devices are
high efficiency 1.5X fractional charge pumps
intended for white LED backlight applications. The
fractional charge pump consists of a linear regula-
tor followed by a 1.5X charge pump. The
AAT3113/13A and AAT3114/14A require only four
external components: two 1F ceramic capacitors
for the charge pump flying capacitors (C1 and C2),
one 1F ceramic capacitor for C
IN
, and one 0.33F
to 1F ceramic capacitor for C
OUT
. The charge
pump output is converted into four or six constant
current outputs (D1 to D4 or D6) to drive four or six
individual LEDs with a maximum of 20mA each.
The current source output magnitude is controlled
by the EN/SET serial data S
2
Cwire interface. The
interface records rising edges of the EN/SET pin
and decodes them into 32 individual current level
settings each 1dB apart (see Table 1, Current
Level Settings). Code 32 is full scale, and Code 1
is full scale attenuated by 31dB. The modulo 32
interface wraps states back to state 1 after the
32nd clock. With each EN/SET pulse, the output
current increases by 1dB. To decrease the output
current by 1dB, 31 EN/SET clock pulses are
required. The counter can be clocked at speeds up
to 1MHz, so intermediate states are not visible.
The first rising edge of EN/SET enables the IC and
initially sets the output LED current to -31dB, the
lowest setting equal to 525A. Once the final clock
cycle is input for the desired brightness level, the
EN/SET pin is held high to maintain the device out-
put current at the programmed level. The device is
disabled 500s after the EN/SET pin transitions to
a logic low state.

Code
Normalized Current to Full Scale
EN/SET Serial Interface
The current source output magnitude is controlled
by the EN/SET pin using AnalogicTech's Simple
Serial Control (S
2
Cwire) interface. The interface
records rising edges of the EN/SET pin and
decodes them into 32 individual current level set-
tings each 1dB apart. Code 32 is full scale, and
Code 1 is full scale attenuated by 31dB. The mod-
ulo 32 interface wraps states back to state 1 after
the 32nd clock, so 1dB of attenuation is achieved
by clocking the EN/SET pin 31 times (see graph
titled, "I
DIODE
Response -9dB to -10dB"). The
counter can be clocked at speeds up to 1MHz, so
intermediate states are not visible. The first rising
edge of EN/SET enables the IC and initially sets
the output LED current to -31dB, the lowest setting
equal to 525A. Once the final clock cycle is input
for the desired brightness level, the EN/SET pin is
held high to maintain the device output current at
the programmed level. The device is disabled
500s after the EN/SET pin transitions to a logic
low state.
The EN/SET timing is designed to accommodate a
wide range of data rates. After the first rising edge
of EN/SET, the charge pump is enabled and reach-
es full capacity after the soft-start time (T
SS
). During
the soft-start time, multiple clock pulses may be
entered on the EN/SET pin to set the final output
current level with a single burst of clocks.
Alternatively, the EN/SET clock pulses may be
entered one at a time to gradually increase the LED
brightness over any desired time period. A constant
current is sourced as long as EN/SET remains in a
logic high state. The current source outputs are
switched off after EN/SET has remained in a low
state for at least the t
OFF
timeout period.
LED Selection
AAT3113/13A and AAT3114/14A devices are
designed to drive white LEDs with forward voltages
of less than 4.2V. Since the D1:D6 output current
sources are matched with negligible voltage
dependence, the LED brightness will be matched
regardless of their forward voltage matching.
Charge Pump Efficiency
The AAT3113/13A and AAT3114/14A devices are
fractional charge pumps. The efficiency (
) can be
simply defined as a linear voltage regulator with an
effective output voltage that is equal to one and a
half times the input voltage. Efficiency (
) for an
ideal 1.5X charge pump can typically be expressed
as the output power divided by the input power:
In addition, with an ideal 1.5X charge pump, the
output current may be expressed as 2/3 of the
input current. The expression to define the ideal
efficiency (
) can be rewritten as:
-or-
For a charge pump with an output of 5 volts and a
nominal input of 3.5 volts, the theoretical efficiency
is 95%. Due to internal switching losses and IC
quiescent current consumption, the actual efficien-
cy can be measured at 93%. These figures are in
close agreement for output load conditions from

. Refer to the Typical
Characteristics section for measured plots of effi-
ciency versus input voltage and output load current
for the given charge pump output voltage options.
Power Efficiency and Device Evaluation
The charge pump efficiency discussion of the previ-
ous section only accounts for efficiency of the
charge pump section itself. Due to the unique cir-
cuit architecture and design of the AAT3113/13A
and AAT3114/14A, it is very difficult to measure effi-
ciency in terms of a percent value comparing input
power over output power. Since the device outputs
are pure constant current sources, it is difficult to
measure the output voltage for a given output (D1
to D6) to derive an output power measurement. For
any given application, white LED forward voltage
levels can differ, yet the output drive current will be
maintained as a constant. This makes quantifying
output power a difficult task when taken in the con-
text of comparing to other white LED driver circuit
topologies. A better way to quantify total device effi-
ciency is to observe the total input power to the
device for a given LED current drive level. The best
white LED driver for a given application should be
based on trade-offs of size, external components
count, reliability, operating range, and total energy
usage...not just "% efficiency."
Capacitor Selection
Careful selection of the four external capacitors
C
IN
, C1, C2, and C
OUT
is important because they
will affect turn-on time, output ripple, and transient
performance. Optimum performance will be
obtained when low equivalent series resistance
(ESR) ceramic capacitors are used. In general,
low ESR may be defined as less than 100m
. A
value of 1F for all four capacitors is a good start-
ing point when choosing capacitors. If the LED cur-
rent sources are only programmed for minimal cur-
rent levels, then the capacitor size may be
decreased.
Capacitor Characteristics
Ceramic composition capacitors are highly recom-
mended over all other types of capacitors for use
with the AAT3113/13A and AAT3114/14A products.
Ceramic capacitors offer many advantages over
their tantalum and aluminum electrolytic counter-
parts. A ceramic capacitor typically has very low
ESR, is lowest cost, has a smaller PCB footprint,
and is non-polarized. Low ESR ceramic capacitors
help maximize charge pump transient response.
Since ceramic capacitors are non-polarized, they
are not prone to incorrect connection damage.
Equivalent Series Resistance: ESR is an impor-
tant characteristic to consider when selecting a
capacitor. ESR is a resistance internal to a capac-
itor that is caused by the leads, internal connec-
tions, size or area, material composition, and ambi-
ent temperature. Capacitor ESR is typically meas-
ured in milliohms for ceramic capacitors and can
range to more than several ohms for tantalum or
aluminum electrolytic capacitors.
Ceramic Capacitor Materials: Ceramic capacitors
less than 0.1
F are typically made from NPO or
C0G materials. NPO and C0G materials typically
have tight tolerance and are stable over tempera-
ture. Large capacitor values are typically composed
of X7R, X5R, Z5U, or Y5V dielectric materials.
Large ceramic capacitors, typically greater than
2.2
F, are often available in low-cost Y5V and Z5U
dielectrics, but large capacitors are not required in
AAT3113/13A or AAT3114/14A applications.
Capacitor area is another contributor to ESR.
Capacitors that are physically large will have a
lower ESR when compared to an equivalent mate-
rial smaller capacitor. These larger devices can
improve circuit transient response when compared
to an equal value capacitor in a smaller package
size.

Test Current/Channel Disable
Each channel of the output is equipped with a test
current function. A small amount of current (~2A)
is injected into each output current source to detect
the presence of load (LED). Unused channels that
are tied to ground or LED load fail short will be auto-
matically diasbled instead of wasting the pro-
grammed output current. The test current in the
AAT3113A and AAT3114A are higher (~150A) to
accommodate LEDs with lower impedance in failure
mode.
Thermal Protection
The AAT3113/13A and AAT3114/14A have a ther-
mal protection circuit that will shut down the charge
pump and current outputs if the die temperature
rises above the thermal limit. However, thermal
resistance of the QFN package is so low that if, in
the case of the AAT3114/14A, all six outputs are
shorted to ground at maximum 20mA output level,
the die temperature will not rise sufficiently to trip
the thermal protection. The thermal protection will
only trip if C
OUT
is shorted to ground and the ambi-
ent temperature is high.
Driving white LED display module backlights
and individual white LEDs connected in parallel:
The AAT3114/14A D1 to D6 outputs are true con-
stant current sources capable of driving up to 20mA
each over the operation input voltage range. Since
these outputs are true constant current sources,
they may be connected in parallel to drive a single
power output. Any combination of outputs (D1 to
D6) may be connected in parallel. The maximum
total output current is a sum of how many current
sources are parallel connected. This feature is par-
ticularly useful to power pre-manufactured display
modules that are pre-wired with white LED back-
lights connected in a parallel circuit configuration. All
outputs can be connected in parallel to drive groups
of LEDs as well. The internal current source refer-
ence circuit bases feedback from current sensed on
the D1 output. For best operation, the only require-
ment for this application is that the output D1 should
always be connected to the load circuit.
