Overview

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.

Features

Full TV design including interleave CrM PFC, two LLCs for backlight and system power design
Planar transformer design in LLC stages
Slim power design with 10mm height
Daughter boards design for LLC stages: check each module independently before system assembly
<150mW no load standby power, and <300mW input power with 165mW output power
Primary switch device by GaN for high frequency capability
No load condition without burst mode to eliminate audible noise
