Introduction

AI Translation

3843 is a current-mode PWM IC designed for switched-mode 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
  • Built-in UVLO circuit
  • Low startup current (typical 70uA)
  • Stable internal voltage reference
  • High-current push-pull output (drive current up to 1A)
  • Operating frequency up to 500kHz
  • Automatic negative feedback compensation circuit
  • Double pulse suppression
  • Excellent load transient response
