TEA1610P; TEA1610T
Zero-voltage-switching resonant converter controller
Rev. 03 — 26 March 2007
1. General description
The TEA1610 is a monolithic integrated circuit implemented in a high-voltage Diffusion
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 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.
