Description
TSM1015 is a highly integrated solution for SMPS
applications requiring CV (constant voltage) and
CC (constant current) mode.
TSM1015 integrates one voltage reference and
two operational amplifiers.
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.
TSM1015 is pin to pin compatible with TSM103
and represents an enhanced version low
consumption.
