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.
