The PT6200 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 shutdown mode is less
than 100A.
