FEATURES
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.
