Description

This reference design provides the information for a flat screen TV power design with a height limitation of 10mm. The design uses an interleave transition-mode (TM) power factor correction (PFC) for the main board, and two separate LLC resonant daughter boards which can be changed and were designed based on the planar transformer. The typical capability of the reference design is 300W, and the peak capability is 540W.
