• Integrated high voltage level-shift function

• Integrated high voltage bootstrap diode

• Transconductance error amplifier for ultra high-ohmic

regulation feedback

• Latched shut-down circuit for overcurrent and

overvoltage protection

GENERAL DESCRIPTION

The TEA1610 is a monolithic integrated circuit

implemented in a high-voltage 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.
