TEA1611T Zero voltage switching resonant converter controller Rev. 01 7 September 2009 Product data sheet 1. General description The TEA1611T is a monolithic integrated circuit implemented in a high voltage Diffusion Metal Oxide Semiconductor (DMOS) process, which is a high voltage controller for a zero voltage switching resonant converter. The IC provides the drive function for two discrete power MOSFETs in a half-bridge configuration. It also includes a level-shift circuit, an oscillator with accurately programmable frequency range, a latched shut-down function and a transconductance error amplifier. To guarantee an accurate 50 % switching duty factor, the oscillator signal passes through a divide-by-two flip-flop before being fed to the output drivers. The circuit is very �� [ ... ]
