DESCRIPTION
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
each PWM is limited to 50% maximum duty cycle,
insuring adequate off-time to reset magnetic
elements.

(2) Processing is per the Texas Instruments commercial production baseline and is in compliance with the Texas Instruments Quality
Control System in effect at the time of manufacture. Electrical screening consists of DC parametric and functional testing at room
temperature only. Unless otherwise specified by Texas Instruments AC performance and performance over temperature is not
warranted. Visual Inspection is performed in accordance with MIL-STD-883 Test Method 2010 Condition B at 75X minimum.
