FEATURES  
DESCRIPTION  
The UCC2895-Q1 is  
Qualified for Automotive Applications  
Programmable Output Turn-On Delay  
Bidirectional Oscillator Synchronization  
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.  
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  
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.  
Operation to 1 MHz  
Typical 5-mA Operating Current at 500 kHz  
Very Low 150-μA Current During Undervoltage  
Lockout (UVLO)  
APPLICATIONS  
Phase-Shifted Full-Bridge Converters  
Off-Line, Telecom, Datacom, and Servers  
Distributed Power Architecture  
High-Density Power Modules
