BiCMOS Advanced Phase Shift PWM Controller  
FEATURES  
DESCRIPTION  
Programmable Output Turn-on Delay  
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 modula-  
tion in conjunction with resonant zero-voltage switching to provide high effi-  
ciency at high frequencies. The part can be used either as a voltage mode  
or current mode controller.  
Adaptive Delay Set  
Bidirectional Oscillator Synchronization  
Capability for Voltage Mode or Current  
Mode Control  
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 capabil-  
ity. 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.  
Programmable Soft Start/Soft Stop  
and Chip Disable via a Single Pin  
0% to 100% Duty Cycle Control  
7MHz Error Amplifier  
Operation to 1MHz  
The UCC3895 and UCC2895 are offered in the 20 pin SOIC (DW) pack-  
age, 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).  
Low Active Current Consumption  
(5mA Typical @ 500kHz)  
Very Low Current Consumption  
During Undervoltage Lock-out  
(150mA typical)
