LM5025A Active Clamp Voltage Mode PWM Controller
LM5025A Active Clamp Voltage Mode PWM Controller
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.
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 features necessary to implement power converters utilizing the Active Clamp / Reset technique.
