UC3844D - CURRENTMODE PWM CONTROLLER

STMicroelectronics

Datasheet Details

TheUC3842/3/4/5family of controlICs provides the necessary

to implement off-line or DC to DC fixed frequency current mode control schemes with a minimal externalparts count. Internallyimplementedcircuits include undervoltagelockout featuring start-up current less than 1 mA, a precision reference trimmed for accuracy at the error amp input, logic to insure latched operation, a PWM comparatorwhich also providescurrentlimit control,and a totem pole output stage designed to source or sink high peak current. The output stage, suitable for driving N-Channel M.
