DESCRIPTION
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 increased to 0.5V
- The CS2 filter discharge device is disabled
- The VCC regulator continues to operate...
