Introduction

AI Translation

The UC3844 is a pulse width integrated circuit with current control mode for switching power supply. Compared with the voltage control mode, it has many advantages in load response and linear adjustment. This device is available in SOP8 package and DIP8 package.

Features

AI Translation
  • Internally Undervoltage Lockout Circuit
  • Low Startup and Operating Current (0.26mA at typical)
  • Maximum Duty Cycle Control
  • High current push-pull output (drive current up to 1A)
  • Operating Frequency: 500kHz
  • Automatic Feed Forward Compensation
  • Double-pulse Suppression
  • Enhanced Load-response Characteristics

Applications

AI Translation
  • Switching regulators of any polarity
  • Transformer-coupled DC-DC converters
