Synchronous Rectifier Driver
DESCRIPTION
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.
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.
