DESCRIPTION
The UC1715 is a high speed driver 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 this driver. The delay
pins also have true zero voltage sensing capability which allows immediate activation of the corresponding switch
when zero voltage is applied. This device requires a PWM-type input to operate and can be interfaced with
commonly available PWM controllers.
