1FEATURES DESCRIPTIONThese 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 switch
and 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 to
1-A Sinkfacilitate the soft switching transitions, independently
• Time Delays Between Power and Auxiliary programmable delays between the two output
Outputs Independently Programmable from50 waveforms are provided on these drivers. The delay
to 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.
