1. General description
2. Features
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 flexible and enables a broad range of applications for different mains
voltages.
