DESCRIPTION
The UCC3895 is a phase shift 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 pulse-width modulation in conjunction with resonant zero-voltage switching to provide high efficiency at high frequencies. The part can be used either as a voltage mode or current mode controller.
While the UCC3895 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. Since it is built in BCDMOS, it operates with dramatically less supply current than it's bipolar counterparts.The UCC3895 can operate with a maximum clock frequency of 1MHz.
The UCC3895 and UCC2895 are offered in the 20 pin SOIC (DW) package,20 pin PDIP(N) package, 20 pin TSSOP (PW) package, and 20 pin PLCC(Q). The UCC1895 is offered in the 20 pin CDIP(J) package, and 20 pin CLCC package (L).
