UC2714

These two families of high speed drivers are designed to provide drive aveforms for complementary switches. Complementary switch configurations re commonly used in synchronous rectification circuits and active lamp/reset circuits, which can provide zero voltage switching. In order to acilitate the soft switching transitions, independently programmable delays etween the two output waveforms are provided on these drivers. he delay pins also have true zero voltage sensing capability which allows mmediate activation of the corresponding switch when zero voltage is applied. hese devices require a PWM-type input to operate and can be interfaced ith commonly available PWM controllers.

In the UC1714 series, the AUX output is inverted to allow driving a -channel MOSFET. In the UC1715 series, the two outputs are configured n a true complementary fashion.
