Introduction

AI Translation

UC2845 is a fixed-frequency current-mode PWM controller designed for off-line and DC-DC converter applications. This IC integrates an oscillator, temperature-compensated reference voltage source, high-gain error amplifier, current-sensing comparator, and a high-current totem-pole output suitable for driving power MOSFETs. Protection features include input and reference undervoltage lockout with hysteresis, cycle-by-cycle current limiting, a latch for single-pulse metering, and a flip-flop that alternately inhibits the output each oscillator cycle, allowing the output dead time to be programmed between 50% and 70%. The UC2845 is optimized for lower-voltage applications, with UVLO thresholds of 8.2V (turn-on) and 7.6V (turn-off).

Features

AI Translation
  • Current-mode operation, output switching frequency up to 500 kHz
  • Output dead time adjustable from 50% to 70%
  • Automatic feed-forward compensation
  • Latching PWM for cycle-by-cycle current limiting
  • Internal trimmed reference voltage with undervoltage lockout
  • High-current push-pull output (drive current up to 1A)
  • Undervoltage lockout with hysteresis
  • Low startup and operating current (< 0.5 mA)

Applications

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