General description
The TEA1612T is a monolithic integrated circuit implemented in a high-voltage double
Diffused Metal Oxide Semiconductor (DMOS) process. The circuit 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 conguration. It also includes a
level-shift circuit, an oscillator with an accurately-programmable frequency range, a
latched shut-down function, burst mode operation and a transconductance error amplier.
The oscillator signal passes through a divide-by-two ip-op before being fed to the output
drivers in order to guarantee an accurate 50 % switching duty factor.
The circuit is very exible and enables a broad range of applications for different mains
voltages.
