UC3843A Datasheet - UTC

UC3843A CURRENT MODE PWM CONTROLLER

The UTC UC3842A/3843A are high performance fixed frequency current mode controllers that specifically designed for Off-Line and DC to DC converter applications with minimal external parts count. The differences between UC3842A and UC3843A are the under-voltage lockout thresholds. The UC3842A ideally.
