The PT6100 Series is a line of High-Perfor-
mance 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 100A.

* 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 100F electrolytic or tantalum output capacitor for proper operation in all applications.
