LM5026
Overview
The LM5026 PWM controller contains all of the features necessary to implement power converters utilizing the active clamp and reset technique with current-mode control. With the active clamp technique, higher efficiencies and greater power densities can be realized compared to conventional catch winding or RDC clamp and reset techniques.
