The PT6100 Series is a line of High-
Performance 1 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 shutdown mode is less than 100µA.

* ISR will operate down to no load with reduced specifications.
** Input voltage cannot exceed 30V when the inhibit function is used. ***See Thermal Derating chart.
Note:
The PT6100 Series requires a 100µF electrolytic or tantalum output capacitor for proper operation in all applications.

Note 1:
All data listed in the above graphs, except for derating data, has been developed from actual products tested at 25°C. This data is considered typical data for the ISR.
Note 2:
Thermal derating graphs are developed in free air convection cooling of 40-60 LFM. (See Thermal Application Notes.)

Adjusting the Output Voltage of the Wide Input
Range Bus ISRs
Figure 1
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

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.
The values of
(R1)
[adjust down], and R2 [adjust up], can
also be calculated using the following formulae.
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

. Any capacitance added to the V

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.
