Small SIP Footprint
Wide Input Range
The PT6210 Series is a line of
High-Performance 2 Amp, 12-Pin SIP
(Single In-line Package) Integrated
Switching Regulators (ISRs) designed
to meet the on-board power conversion
needs of battery powered
or other equipment requiring high
efficiency and small size. This high
performance ISR family offers a unique
combination of features combining 90%
typical efficiency with open-collector
on/off control and adjustable output
voltage. Quiescent current in the shut-
down mode is typically less than 100A.

More Application Notes
Adjusting the Output Voltage of the Wide Input
Range Bus ISRs
The output voltage of the Power Trends' Wide Input Range
Series ISRs may be adjusted higher or lower than the factory
trimmed pre-set voltage with the addition of a single external
resistor. Table 1 accordingly gives the allowable adjustment
range for each model for either series as V
a
(min) and V
a
(max).
Adjust Up:
An increase in the output voltage is obtained by
adding a resistor R2, between pin 12 (V
o
adjust) and pins 5-8
(GND).
Adjust Down:
Add a resistor
(R1)
, between pin 12 (V
o
adjust)
and pins 9-11(V
out
).
Refer to Figure 1 and Table 2 for both the placement and value
of the required resistor; either
(R1)
or R2 as appropriate.
Notes:
1. Use only a single 1% resistor in either the
(R1)
or R2 loca-
tion. Place the resistor as close to the ISR as possible.
2. Never connect capacitors from V
o
adjust to either GND or
V
out
. Any capacitance added to the V
o
adjust pin will affect
the stability of the ISR.
4. Adjustments to the output voltage may place additional
limits on the maximum and minimum input voltage for the
part. The revised maximum and minimum input voltage
limits must comply with the following requirements. Note
that the minimum input voltage limits are also model depen-
dant.
