DESCRIPTION

The TSM1011 is a highly integrated solution for

SMPS

applications

requiring

CV

(constant

voltage) and CC (constant current) modes.

The TSM1011 integrates one voltage reference

and two operational amplifiers (with ORed outputs

—common collectors).

The

voltage

reference

combined

with

one

operational amplifier makes it an ideal voltage

controller.

The

other

operational

amplifier,

combined with few external resistors and the

voltage reference, can be used as a current

limiter.

APPLICATIONS

s

Adapters

s

Battery chargers
