LM5025B Product details

Description

The LM5025B is a functional variant of the LM5025 active clamp PWM controller.. 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 when the line UVLO is below the threshold of normal operation. The VREF regula.
