Texas Instruments PFCLLCSREVM034 AC to Isolated DC Evaluation Module

Texas Instruments PFCLLCSREVM034 AC to Isolated DC Evaluation Module (EVM) is for evaluation of 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.

Features

  • Low-cost single layer PCB
  • AC Input voltage from 90Vrms to 264Vrms
  • Regulated 12VDC typical output
  • Full-load power of 168W, or full-load current of 14A
  • High efficiency
  • Optimized low power features enable extremely low-standby power
  • Advanced burst mode with burst soft-on and soft-off for minimized audible noise
  • X-capacitor discharge
  • Test points to facilitate device and topology evaluation

Required Equipment
