... Rev. 01 — 7 September 2009 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 confi ...
