Description
General part information
EVAL-STCH03-45W Series
The STCH03 current-mode controller is designed for an offline quasi-resonant ZVS (zero-voltage-switching at switch turn-on) flyback converter.
It combines a high-performance low-voltage PWM controller chip and a 650V HV start-up cell in the same package.
Constant output voltage (CV) regulation loop is achieved by secondary side feedback, the output voltage information is transfered via an optocoupler on the FB pin of the STCH03 to get the selected output voltage.
