Texas Instruments UCC29950 | Demoboard TIDA-00704

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.
