UC3845T - (UC3842T - UC3845T) HIGH PERFORMANCE CURRENT MODE PWM CONTROLLER

Download the UC3845T datasheet PDF. This datasheet also covers the UC3843T variant, as both devices belong to the same (uc3842t - uc3845t) high performance current mode pwm controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The UC384XT family of control ICs 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 a trimmed oscillator for precise DUTY CYCLE.
