The UCC3810-DIE 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-DIE provides perfect
synchronization between two PWMs by using the
same oscillator. The oscillator’s sawtooth waveform
can be used for slope compensation if required.
Using a toggle flip-flop to alternate between
modulators, the UCC3810-DIE ensures that one
PWM does not slave, interfere, or otherwise affect the
other PWM. This toggle flip-flop also ensures that …
