Design LM5026
SNVS363E – AUGUST 2005 – REVISED NOVEMBER 2015 LM5026 Active Clamp Current Mode PWM Controller
1 Features 3 Description 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.
Two control outputs are provided, the main power
switch control (OUT_A) and the active clamp switch
control (OUT_B). The device can be configured to
control either a P-Channel or N-Channel clamp
switch. The main gate driver features a compound
configuration, consisting of both MOS and Bipolar
devices, providing superior gate drive characteristics.
The LM5026 can be configured to operate with bias …
