General Description
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.
Key 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 power switch control (OUT_A) and the active clamp switch control (OUT_B). The two internal compound gate drivers parallel both MOS and Bipolar devices, providing superior gate drive characteristics. Thi.
