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.
