PHASE SHIFT RESONANT CONTROLLER  
FEATURES  
DESCRIPTION  
Programmable Output Turn On Delay; Zero  
Delay Available  
The UC3879 controls a bridge power stage by phase  
shifting the switching of one half-bridge with respect  
to the other. This allows constant frequency pulse  
width modulation in combination with resonant,  
Compatible with Voltage Mode or Current  
Mode Topologies  
zero-voltage  
switching  
for  
high  
efficiency  
Practical Operation at Switching Frequencies  
to 300 kHz  
performance. The UC3879 can be configured to  
provide control in either voltage mode or current  
mode operation, with overcurrent shutdown for fast  
fault protection.  
10-MHz Error Amplifier  
Pin Programmable Undervoltage Lockout  
Low Startup Current – 150 µA  
Soft Start Control  
Independently programmable time delays provide  
dead-time at the turn-on of each output stage,  
allowing time for each resonant switching interval.  
Outputs Active Low During UVLO
