UC1824 Datasheet High Speed Pwm Controller

Manufacturer: Texas Instruments

Overview: www.ti.com UC1824 UC2824 UC3824 SLUS326A – MARCH 1997 – REVISED JULY 2007 HIGH SPEED PWM.

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.

This controller is designed for use in either current mode or voltage mode systems with the capability for input voltage feed-forward.

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.
