BiCMOS Advanced Phase-Shift PWM Controller

Check for Samples: UCC1895, UCC2895, UCC3895

FEATURES

DESCRIPTION

The UCC3895 is a phase-shift PWM controller that

•

Programmable-Output Turnon Delay

Adaptive Delay Set

implements control of a full-bridge power stage by

phase shifting the switching of one half-bridge with

respect to the other. The device allows constant

frequency pulse-width modulation in conjunction with

resonant zero-voltage switching to provide high

efficiency at high frequencies. The part is used either

as a voltage-mode or current-mode controller.

Bidirectional Oscillator Synchronization

Voltage-Mode, Peak Current-Mode, or Average

Current-Mode Control

•

Programmable Softstart, Softstop and Chip

Disable via a Single Pin

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. Because the device is built using

the BCDMOS process, it operates with dramatically

less supply current than it’s bipolar counterparts. The

UCC3895 operates with a maximum clock frequency

of 1 MHz.
