Complementary Switch FET Drivers  
FEATURES  
DESCRIPTION  
Single Input (PWM and TTL  
Compatible)  
These two families of high speed drivers are designed to provide drive  
waveforms for complementary switches. Complementary switch configura-  
tions are commonly used in synchronous rectification circuits and active  
clamp/reset circuits, which can provide zero voltage switching. In order to  
facilitate the soft switching transitions, independently programmable de-  
lays between the two output waveforms are provided on these drivers.  
The delay pins also have true zero voltage sensing capability which allows  
immediate activation of the corresponding switch when zero voltage is ap-  
plied. These devices require a PWM-type input to operate and can be in-  
terfaced with commonly available PWM controllers.

Time Delays Between Power and  
Auxiliary Outputs Independently  
Programmable from 50ns to 500ns  
In the UC1714 series, the AUX output is inverted to allow driving a  
p-channel MOSFET. In the UC1715 series, the two outputs are configured  
in a true complementary fashion.
