TYPICAL PERFORMANCE CHARACTERISTICS
(100kHz and 500kHz types are
available only without current limiter)
XC9103/04/05 Series
Ceramic Cap. Compatible
Step-Up DC/DC Converters
Also available without current limiter
Set up freely with a standard
voltage supply of 0.9V (2.0%) &
external components
The XC9103/9104/9105 series are PWM, PWM/PFM auto switching
/manual switching controlled multi-functional step-up DC/DC converter
controllers.
Output will be stable no matter which load capacitors are used but should a
low ESR capacitor be used, RSENSE of about 0.1
will be required and
phase compensation will be achieved. This makes the use of ceramic
capacitors much easier and allows for lower output ripple and reduced PCB
area requirements. Tantalum and electrolytic capacitors can also be used,
in which case, RSENSE becomes unnecessary.
With 0.9V of standard voltage supply internal, and using externally
connected components, output voltage can be set up freely within a range
of 1.5V to 30V. With 300kHz or 180kHz frequencies, the size of the
external components can be reduced. Oscillation frequencies of 100kHz
and 500kHz are also available as custom-designed products.
The XC9103 series are PWM controlled. Control switches from PWM
to PFM during light loads with the XC9104 and the series is highly
efficient from light loads to large output currents. By using external signals,
control of the XC9105 can be alternated between PWM and
PWM/PFM automatic switching and so, control suited to the
application can be selected.
A current limiter circuit is built in to the IC (except with the 100kHz and
500kHz version) and monitors the ripple voltage on the FB pin. Operation
is shut down when the ripple voltage is more than 250mV(180kHz version).
The operations of the IC can be returned to normal with a toggle of the CE
pin or by turning the power supply back on.

With the XC9105 series, the CE pin also serves as a PWM/PFM switching pin. In operation, PWM control is selected when the voltage at the CE pin is
more than VDD -0.2V. On the other hand, PWM/PFM automatic switching control at a duty = 25% is selected when the voltage at the CE pin is less than
VDD -1.0V and more than VCEH.
The overcurrent limit circuit of this IC is designed to monitor the ripple voltage so please select your external components carefully to prevent VLMT
being reached under low temperature conditions as well as normal operating conditions. Following current limiter circuit operations, which in turn causes
the IC's operations to stop, the operations of the IC can be returned to normal with a toggle of the CE pin or by turning the power supply back on.

HOW TO USE
Note:
* Please select your external components carefully (refer to the page 8).
By using external signals, the control of the XC9105 series can be switched between PWM control
and PWM/PFM automatic switching control. By inputting a voltage of more than VDD -0.2V to the
CE/PWM pin, PWM control can be selected. On the other hand, PWM/PFM automatic switching
control can be selected by inputting a voltage of less than VDD -1.0V.
Insert Rb and CB when using a
bipolar NPN Transistor.
When obtaining VDD from a source other than
VOUT, please insert a capacitor CIN between
the VDD pin and the GND pin in order to provide
stabler operations.
Please wire CL & CIN between the VOUT/VDD
pin and the GND pin. Strengthen the wiring
sufficiently.
With the XC9105, by connecting resistors of the same value (RM1, RM2) as shown in the diagram
to the left, it is possible to obtain chip disable with SCE ON and, SPWM ON or OFF, PWM/PFM
auto switching at Duty=25% with SCE OFF & SPWM ON, & PFM control with both switches OFF.
When operating at VDD -1.8V and below (stepping-up from VIN=0.9V), it is necessary to pull-up to
VDD in order to allow the CE/PWM pin reach the VCEH voltage level. Please make sure that the
IC is in PWM control (SPWM=OFF) when operations start. If SPWM is ON, there are times when
chip enable might not operate.

Error Amplifier is designed to monitor the output voltage, comparing the feedback voltage (FB) with the reference voltage Vref. In response to feedback
of a voltage lower than the reference voltage Vref, the output voltage of the error amp. decreases.
This circuit generates the internal reference clock.
The PWM comparator compares outputs from the Error Amp. and saw-tooth waveform. When the voltage from the Error Amp's output is low, the
external switch will be set to ON.
This circuit generates PFM pulses.
The PWM/PFM automatic switching mode switches between PWM and PFM automatically depending on the load. The PWM/PFM automatic switching
mode is selected when the voltage of the CE pin is less than VDD - 1.0V, and the control switches between PWM and PFM automatically depending on
the load. PWM/PFM control turns into PFM control when threshold voltage becomes lower than voltage of error amps. PWM control mode is selected
when the voltage of the CE pin is more than VDD - 0.2V. Noise is easily reduced with PWM control since the switching frequency is fixed. The series is
suitable for noise sensitive portable audio equipment as PWM control can suppress noise during operation and PWM/PFM switching control can reduce
consumption current during light load in stand-by.
The reference voltage, Vref (FB pin voltage)=0.9V, is adjusted and fixed by laser trimming (for output voltage settings, please refer to the notes on page
8). To protect against inrush current, when the power is switched on, and also to protect against voltage overshoot, soft-start time is set internally to
10ms. It should be noted, however, that this circuit does not protect the load capacitor (CL) from inrush current. With the Vref voltage limited and
depending upon the input to the error amps, the operation maintains a balance between the two inputs of the error amps and controls the EXT pin's ON
time so that it doesn't increase more than is necessary.
This function controls the operation and shutdown of the IC. When the voltage of the CE pin is 0.2V or less, the mode will be disable, the channel's
operations will stop and the EXT1 pin will be kept at a low level (the external N-type MOSFET will be OFF). When the IC is in a state of disable, current
consumption will be no more than 1.0
A.
When the CE pin's voltage is 0.65V or more, the mode will be enable and operations will recommence.
When applying voltage to VDD through CE pin with the series' B type product, the
limiter circuit may operate when a power supply is on, and the operation may not
start. In this case, as the right circuit indicates, please connect a resistor and a
capacitor with the CE pin. By the time constant, the CE pin will be chip enable after
VDD rise so that IC will be in the stable condition.

RSENSE:

CFB:
Set up so that fzfb = 100kHz.
Output voltage can be set by adding external split resistors. Output voltage is determined by the following equation, based on the values of RFB1 and
RFB2. The sum of RFB1 and RFB2 should normally be 2 M
or less.
The value of CFB1, speed-up capacitor for phase compensation, should result in fzfb = 1/(2
CFB
RFB1) equal to 5 to 30kHz. Adjustments
are required depending on the application, value of inductance (L), and value of load capacity (CL).
The circuit of the XC9103/04/05 series is organized by a specialized circuit which reenacts negative feedback of both voltage and current. Also
by insertion of approximately 100m
of a low and inexpensive sense resistor as current sense, a high degree of stability is possible even using
a ceramic capacitor, a condition which used to be difficult to achieve. Compared to a tantalum condenser, because the series can be operated
in a very small capacity, it is suited to use of the ceramic capacitor which is cheap and small.
Note* : As the breakdown voltage of XP161A1355 is 8V, take
care with the power supply voltage. With output voltages over
6V, use the XP161A1265 with a breakdown voltage of 12V.
VST1: XP161A1355 PR =1.2V (max.)
XP161A1265PR = 1.5V (max.)
