UC3824 - HIGH SPEED PWM CONTROLLER

General Description

The UC1824 family of PWM control devices is optimized for high frequency switched mode power supply applications.

Particular care was given to minimizing propagation delays through the comparators and logic circuitry while maximizing bandwidth and slew rate of the error amplifier.

Key Features

  • Complementary Outputs.
  • Practical Operation Switching Frequencies to 1 MHz.
  • 50-ns Propagation Delay to Output.
  • High Current Dual Totem Pole Outputs (1.5 A Peak).
  • Wide Bandwidth Error Amplifier.
  • Fully Latched Logic With Double Pulse Suppression.
  • Pulse-by-Pulse Current Limiting.
  • Soft Start/Maximum Duty Cycle Control.
  • Under-Voltage Lockout with Hysteresis.
  • Low Start Up Current (1.1 mA).
  • Trimmed Bandga.
