Single Ended Active Clamp/Reset PWM  
FEATURES  
DESCRIPTION  
Provides Auxiliary Switch Activation  
Complementary to Main Power  
Switch Drive  
The UCC3580 family of PWM controllers is designed to implement a variety  
of active clamp/reset and synchronous rectifier switching converter topolo-  
gies. While containing all the necessary functions for fixed frequency, high  
performance pulse width modulation, the additional feature of this design is  
the inclusion of an auxiliary switch driver which complements the main  
power switch, and with a programmable deadtime or delay between each  
transition. The active clamp/reset technique allows operation of single  
ended converters beyond 50% duty cycle while reducing voltage stresses  
on the switches, and allows a greater flux swing for the power transformer.  
This approach also allows a reduction in switching losses by recovering en-  
ergy stored in parasitic elements such as leakage inductance and switch  
capacitance.  
Programmable deadtime (Turn-on  
Delay) Between Activation of Each  
Switch  
Voltage Mode Control with  
Feedforward Operation  
Programmable Limits for Both  
Transformer Volt- Second Product  
and PWM Duty Cycle  
The oscillator is programmed with two resistors and a capacitor to set  
switching frequency and maximum duty cycle. A separate synchronized  
ramp provides a voltage feedforward pulse width modulation and a pro-  
grammed maximum volt-second limit. The generated clock from the oscilla-  
tor contains both frequency and maximum duty cycle information.  
High Current Gate Driver for Both  
Main and Auxiliary Outputs  
Multiple Protection Features with  
Latched Shutdown and Soft Restart  
Low Supply Current (100 mA Startup,  
1.5 mA Operation)
