LM5025B Datasheet (Texas Instruments)

LM5025B, PWM Controller

The LM5025B is a functional variant of the LM5025 active clamp PWM controller.

The functional differences of the LM5025B are as follows: * The maximum PWM duty cycle is limited to less than 75% to reduce voltage stress on the power MOSFETs.

* The CS2 hiccup mode threshold is increase
