Onsemi 7M0880 Power Switch Transistor

The  Fairchild  Power  Switch  FS7M-series  is  an  integrated Pulse Width Modulator (PWM) and Sense FET specifically designed  for  high  performance  offline  Switch  Mode  Power Supplies  (SMPS)  with  minimal  external  components.  This device   is   an   integrated   high   voltage   power   switching regulator  which  combine  an  avalanche  rugged  Sense  FET with a current mode PWM control block. The PWM controller includes  integrated  fixed  frequency  oscillator,  under  voltage lockout,  leading  edge  blanking  (LEB),  optimized  gate  driver ,soft  start,  temperature  compensated  precise  current  sources for   a   loop   compensation   and   self   protection   circuitry. Compared   with   discrete   MOSFET   and   PWM   controller solution,  it  can  reduce  total  cost,  component  count,  size  and weight  simultaneously  increasing  efficiency,  productivity,  and system reliability. This device is a basic platform well suited for cost effective designs of flyback and forward converters.
