LM5027
Overview
The LM5027 pulse-width modulation (PWM) controller contains all of the 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.

- Internal 105V Rated Start-Up Bias Regulator
- Programmable Line Under-Voltage Lockout (UVLO) with Adjustable Hysteresis
- Versatile Dual Mode Over-Current Protection
- Programmable Volt-Second Llimiter
- Programmable Soft-Start
- Programmable Synchronous Rectifier Soft- Start and Stop
- Precise 500mV Over-Current Comparator
- Current Sense Leading Edge Blanking
