Texas Instruments PFCLLCSREVM034 AC to Isolated DC Evaluation Module
Texas Instruments PFCLLCSREVM034 AC to Isolated DC Evaluation Module (EVM) evaluates the UCC28056B, UCC25604, and UCC24624 devices. The evaluation module is a 168W AC/DC supply with a transition-mode power-factor correction front end and isolated half-bridge LLC resonant converter with synchronous rectification. The Texas Instruments PFCLLCSREVM034 accepts AC input from 90Vrms to 264Vrms and outputs 12VDC with 168W full-load output power.
