UC2843A - CURRENT MODE PWM CONTROLLER

Download the UC2843A datasheet PDF. This datasheet also covers the UC2842A variant, as both devices belong to the same current mode pwm controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The UC184xA family of control ICs provides all the necessary

Key Features

  • to implement off-line fixed-frequency, current-mode switching power supplies with a minimum of external components. The current mode architecture demonstrates improved load regulation, pulse-by-pulse current limiting and inherent protection of the power supply output switch. The IC includes: A bandgap reference trimmed to ±1% accuracy, an error amplifier, a current sense comparator with internal clamp to 1V, a high current totem pole output stage for fast switching of power MOSFET's, and an ext.
