General Description

The LM5025A is a functional variant of the LM5025 active clamp PWM controller.

The functional differences of the LM5025A are that the CS1 and CS2 current limit thresholds have been increased to 0.5 V, the internal CS2 filter discharge device has been disabled and no longer operates each clock cycle, and the internal VCC and VREF regulators continue to operate when the line UVLO pin is below threshold.

The LM5025A PWM controller contains all of the

Key Features

  • 1 Internal Start-Up Bias Regulator.
  • 3-A Compound Main Gate Driver.
  • Programmable Line Undervoltage Lockout (UVLO) With Adjustable Hysteresis.
  • Voltage Mode Control With Feedforward.
  • Adjustable Dual Mode Overcurrent Protection.
  • Programmable Overlap or Dead Time Between the Main and Active Clamp Outputs.
  • Volt × Second Clamp.
  • Programmable Soft Start.
  • Leading Edge Blanking.
  • Single Resistor Programmable Oscillator.
