Advanced Phase PWM Controller

Product Description

TI Chips UCC3895DWTR UCCx895 BiCMOS Advanced Phase-Shift PWM Controller

Features
1• Programmable-output turnon delay
• Adaptive delay set
• Bidirectional oscillator synchronization
• Voltage-mode, peak current-mode, or average
current-mode control
• Programmable soft start, soft stop, and chip
disable via a single pin
• 0% to 100% duty-cycle control
• 7-MHz error amplifier
• Operation to 1 MHz
• Typical 5-mA operating current at 500 kHz
• Very low 150-μA current during UVLO

Applications
• Phase-shifted full-bridge converters
• Off-line, telecom, datacom, and servers
• Distributed power architecture
• High-density power modules

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. 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.
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.
