UCC2895-EP 增强型产品 Bicmos 高级相移 Pwm 控制器

The UCC2895-EP is a phase-shift pulse-width modulation (PWM) controller that implements control of a full-bridge power stage by phase shifting the switching of one half bridge with respect to the other. It allows constant frequency PWM in conjunction with resonant zero-voltage switching to provide high efficiency at high frequencies. The device can be used either as a voltage-mode or current-mode controller.

While the UCC2895-EP maintains the functionality of the UC2875/6/7/8 family, it improves on that controller family with additional features, such as enhanced control logic, adaptive delay set, and shutdown capability. Since the device is built in BCDMOS, it operates with dramatically less supply current than its bipolar counterparts
