Overview

The UC3843 is a fixed frequency current mode PWM controllers. It is specifically designed for Off- Line and DC- DC converter applications. This integrated circuits feature a temperature compensated reference, high gain error amplifier, current sense comparator, and a high Push- pull output ideally suited for driving a power MOSFET. Also included are protective features consisting of input and reference undervoltage lockouts each with hysteresis, allowing deadtimes to be programmed, and a latch for single pulse metering. This device is available in SOP8 package and DIP8 package.

Applications

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

Key features

  • Automatic Feed Forward Compensation
  • Low Startup and Operating Current (<0.5mA)
  • Undervoltage Lockout with Hysteresis
  • Maximum Duty Cycle Control
  • Operating Frequency: 500kHz
