UCC28510 Overview
The UCC28510 series of bination PFC/PWM controllers provide plete control functionality for any off-line power system requiring pliance with the IEC1000−3−2 harmonic reduction requirements. By bining the control and drive signals for the PFC and the PWM stages into a single device, significant performance and cost benefits are gained. By managing the modulation mechanisms of the two stages (leading-edge modulation...
