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.
