LM5025A Datasheet (National Semiconductor) - Active Clamp Voltage Mode PWM Controller

LM5025A, Active Clamp Voltage Mode PWM Controller

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

The functional differences of the LM5025A are: The CS1 and CS2 current limit thresholds have been increased to 0.5V.

The internal CS2 filter discharge device has been disabled and no longer operates each clock cycle.

LM5025A Features

* necessary to implement power converters utilizing the Active Clamp / Reset technique. With the active clamp technique, higher efficiencies and greater power densities can be realized compared to conventional catch winding or RDC clamp / reset techniques. Two control outputs are provided, the main po
