UC3842A Datasheet (UTC) - CURRENT MODE PWM CONTROLLER

UC3842A, 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.
