STR-A6169

STR-A6169概述

IC REG PWM CONV AC-DC 8-DIP

General Descriptions

The  STR-A6100  series  are  power  ICs  for  switching power supplies, incorporating a MOSFET and a current

mode PRC controller IC. PRC  Pulse  Ratio  Control  controls  on-time  with fixed off-time.

The  IC  includes  a  startup  circuit  and  a  standby function to achieve the low standby power. The rich set

of  protection  features  helps  to  realize  low  component counts, and high performance-to-cost power supply.
