DESCRIPTION

TSM1012 is a highly integrated solution for SMPS

applications requiring CV (constant voltage) and

CC (constant current) mode.

TSM1012 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, combined with

few external resistors and the voltage reference,

can be used as a current limiter.
