UTC3843E - PWM CONTROLLER

Download the UTC3843E datasheet PDF. This datasheet also covers the UTC3843D variant, as both devices belong to the same pwm controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The UTC3843D/E provides the necessary

Key Features

  • to implement off-line or DC to DC fixed frequency current mode control schemes with a minimal external parts count. Internally implemented circuits include under-voltage lockout featuring start up current less than 1mA,a precision reference trimmed for accuracy at the error amp input, logic to insure latched operation, a PWM comparator which also provides current limit control,and a totem pole output stage designed to source or sink high peak current. The output stage, suitable for driving N chan.
