The UCC2895-Q1 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.
Although the UCC2895-Q1 maintains the functionality of the UC3875/6/7/8 family and UC3879, it improves on that controller family with additional features such as enhanced control logic, adaptive delay set, and shutdown capability. Because it is built using the BCDMOS process, it operates with dramatically less supply current than its bipolar counterparts. The UCC2895-Q1 can operate with a maximum clock frequency of 1 MHz.
