有源钳位IC UC3715 手册
资料介绍
有源钳位IC FEATURES 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 switch and 2-A Sink configurations are commonly used in 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 Sink facilitate the soft switching transitions, independently • Time Delays Between Power and Auxiliary programmable delays between the two output Outputs Independently Programmable from 50 waveforms are provided on these drivers. The delay to 500-ns pins also have true-zero voltage-sensing capability • Time Delay or True Zero-Voltage Operation which allows immediate activation of the Independently Configurable for Each Output corresponding switch when zero voltage is applied. These devices require a PWM-type input to operate • Switching Frequency to 1 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 output is inverted to • Power Output is Active-Low in Sleep Mode allow driving a p-channel MOSFET. In the UC1715 • Synchronous Rectifier Driver series, the two outputs a
