SNVS363E AUGUST 2005REVISED NOVEMBER 2015  
LM5026 Active Clamp Current Mode PWM Controller  
1 Features  
3 Description  
The LM5026 PWM controller contains all of the  
1
Current-Mode Control  
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  
voltages over a wide input range of 8 V to 100 V.  
Additional features include programmable maximum  
duty cycle, line undervoltage lockout, cycle-by-cycle  
current limit, hiccup mode fault operation with  
adjustable timeout delay, PWM slope compensation,  
Internal 100-V Start-Up Bias Regulator  
3-A Compound Main Gate Driver  
High Bandwidth Optocoupler Interface  
Programmable Line Undervoltage Lockout (UVLO)  
With Adjustable Hysteresis  
Versatile Dual Mode Overcurrent Protection With  
Hiccup Delay Timer
