Single Oscillator Synchronizes Two PWMs  
150-µA Startup Supply Current  
2-mA Operating Supply Current  
Operation to 1 MHz  
The UCC3810 is a high-speed BiCMOS controller  
integrating two synchronized pulse width modulators  
for use in off-line and dc-to-dc power supplies. The  
UCC3810 family provides perfect synchronization  
between two PWMs by usin g the same oscillator.  
The oscillator’s sawtooth waveform can be used for  
slope compensation if required.  
Internal Soft-Start  
Full-Cycle Fault Restart  
Using  
a
toggle flip-flop to alternate between  
Internal Leading-Edge Blanking of the Current  
Sense Signal  
modulators, the UCC3810 ensures that one PWM  
does not slave, interfere, or otherwise affect the  
other PWM. This toggle flip- flop also ensures that  
each PWM is limited to 50% maximum duty cycle,  
insuring adequate off-time to reset magnetic  
elements. This device contains many of the same  
elements of the UC3842 current mode controller  
family, combined with the enhancements of the  
UCC3802. This minimizes power supply parts count.  
Enhancements include leading edge blanking of the  
current sense signals, full cycle fault restart, CMOS  
output drivers, and outputs which remain low even  
when the supply voltage is removed.
