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  
Internal Leading-Edge Blanking of the  
Current Sense Signal  
Using a toggle flip-flop to alternate between  
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.
