SNVS265C – DECEMBER 2003 – REVISED JANUARY 2016 LM5025 Active Clamp Voltage Mode PWM Controller
1 Features 3 Description The LM5025 PWM controller contains all of the
features necessary to implement power converters
using the active clamp and reset technique. The
device can be configured to control either a
P-channel clamp switch or an N-channel clamp
switch. 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. 1 Internal Start-Up Bias Regulator

With Adjustable Hysteresis
Voltage Mode Control With Feed-Forward
Adjustable Dual-Mode Overcurrent Protection
Programmable Overlap or Deadtime Between the
Main and Active Clamp Outputs …
