UC28025 - Economy High-Speed PWM Controller

Download the UC28025 datasheet PDF. This datasheet also covers the UC28023 variant, as both devices belong to the same economy high-speed pwm controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The UC28023 and UC28025 are fixed-frequency PWM controllers optimized for high-frequency switched-mode power-supply applications.

The UC28023 is a single output PWM for single-ended topologies while the UC28025 offers dual alternating outputs for double-ended and full bridge topologies.

Key Features

  • 1 Peak Current Mode, Average Current Mode, or Voltage Mode (With FeedForward) Control Methods.
  • Practical Operation Up to 1 MHz.
  • 50-ns Propagation Delay to Output.
  • ±1.5-A Peak Totem Pole Outputs.
  • 9-V to 30-V Nominal Operational Voltage.
  • Wide Bandwidth Error Amplifier.
  • Fully Latched Logic With Double Pulse Suppression.
  • Pulse-by-Pulse Current Limiting.
  • Programmable Maximum Duty Cycle Control.
  • Undervoltage Lock.
