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.

• High Current Power FET Driver, 1.0A

Source/2A Sink

• Auxiliary Output FET Driver, 0.5A

Source/1A Sink

• 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.

• Time Delay or True Zero-Voltage

Operation Independently Configurable
