Description

The TIDA-00704 is a compact, universal input, 20-32VDC - 320-W output, AC/DC storage battery bank charger for 8 cell LiFePO4 batteries. The circuit consists of a front end continuous conduction mode (CCM) power factor correction (PFC) circuit, followed by an LLC based second stage. The design uses the UCC29950 combo controller which controls both the PFC stage and LLC stage, to achieve a compact and robust control structure. Synchronous rectification based on UCC24610 and low RDSon FETs from Texas instruments help in achieving higher efficiencies. The board comes with an option of a customizable battery charge profiling, by means of adding a small daughter card based on MSP430 controller.

Features
  • Peak overall efficiency of 93%  enables energy saving
  • Uses a single UCC29950 combo controller for controlling both PFC and LLC stages for reduced component count
  • True input power limit to provide greater degree of protection under varying input voltage conditions
  • Low stand-by power (<100mW) to help meet no- load condition limits of energy norm (DoE level VI)
  • Wide input voltage range from 85 VAC to 264 VAC helps in meeting global market needs
