1FEATURES DESCRIPTION

These two families of high speed drivers are• Single Input (PWM and TTL Compatible) designed to provide drive waveforms for• High-Current Power FET Driver, 1-A Source complementary switches. Complementary switchand 2-A Sink configurations are commonly usedin synchronous Auxiliary Output FET Driver, 0.5-A Source and rectification circuits and active clamp/reset circuits,
which provide zero voltage switching. In order to1-A Sink
facilitate the soft switching transitions, independently• Time Delays Between Power and Auxiliary programmable delays between the two outputOutputs Independently Programmable from50 waveforms are provided on these drivers. The delayto 500-ns pins also have true-zero voltage-sensing capability Time Delayor True Zero-Voltage Operation which allows immediate activation of the
Independently Configurable for Each Output
corresponding switch when zero voltageis applied.
These devices requirea PWM-type inputto operate• Switching Frequencyto1 MHz and interface with commonly available PWM• Typical 50-ns Propagation Delays controllers. ENBL Pin Activates 220-μA Sleep Mode In the UC1714 series, the AUX outputis invertedto• Power Outputis Active-Lowin Sleep Mode allow drivinga p-channel MOSFET.In the UC1715 Synchronous Rectifier Driver series, the two outputs are configured ina true
complementary fashion.
