Introduction

AI Translation

3845 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
  • Built-in undervoltage lockout circuit
  • Low startup current (typical 60μA)
  • Stable internal reference voltage source
  • High-current push-pull output (drive current up to 1A)
  • Operating frequency up to 500kHz
  • Automatic negative feedback compensation circuit
  • Double pulse suppression function
  • Excellent load transient response
