Introduction

AI Translation

UC2844 is a current-mode PWM IC designed for switching power supplies. Compared to voltage-mode control, it offers significant advantages in load transient response and line regulation. The device is available in SOP8 and DIP8 packages.

Features

AI Translation
  • Internal undervoltage lockout circuit
  • Low startup and operating current (typical 0.26mA)
  • Maximum duty cycle control
  • High-current totem-pole output (drive current up to 1A)
  • Operating frequency: 500kHz
  • Automatic feed-forward compensation
  • Double pulse suppression
  • Enhanced load response characteristics

Applications

AI Translation
  • Switching regulator with any polarity
  • Transformer-coupled DC-DC converter
