Overview
К1229КП1Р,КП1Н4/ К1229КП2Р,КП2Н4 (UC3714/UC3715) Inv № 216 Complementary Switch FET Drivers February 2001- revised September 2002 DESCRIPTION These two families of high speed drivers are designed to provide drive waveforms for complementary switches.
Complementary switch configurations 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 delays 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 applied.
These devices require a PWM-type input to operate and can be interfaced with commonly available PWM controllers.
In the UC3714 series, the AUX output is inverted to allow driving a p-channel MOSFET.
In the UC3715* series the two outputs are configured in a true complementary fashion.
* The UC3715 series are not produced yet.
