MEASUREMENTS A Typical 250W LCD TV AC-DC Power Supply application with TEA1611 ZVS Half-Bridge Resonant Controller Rev.01 -- March 21th, 2008 NXP Semiconductors MEASUREMENTS TEA1611 250W SMPS measurement report. Document information Info Content Keywords SwingChipTM, TEA1611, Half bridge, LLC Resonant, High efficiency, Zero voltage switching, Resonant frequency, Leakage inductance. Abstract The TEA1611 is a controller of Half Bridge LLC Resonant converter, this report describes a 250W Resonant Switching Mode Power Supply for a typical LCD TV reference design based upon the TEA1611, meanwhile PFC and Standby stage also together in reference design, the no load input power will around 350mW at high mains input, and efficiency higher than 87% for universal mains input with schottky rectifiers, and good cross regulation without any compensation circuit, so there are many advantages suitable for LCD-TV SMPS application, the detail test data will descript in this report.
