TEA1610P; TEA1610T
Zero-voltage-switching resonant converter controller
Rev. 03 — 26 March 2007
Product data sheet
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.

8. Functional description
8.1 Start-up
When the applied voltage at VDD reaches VDD(initial) (see Figure 5), the low side power
switch is turned-on while the high side power switch remains in the non-conducting state.
This start-up output state guarantees the initial charging of the bootstrap capacitor (Cboot)
used for the floating supply of the high side driver.
During start-up, the voltage on the frequency capacitor (Cf) is zero and defines the
start-up state. The output voltage of the error amplifier is kept constant (typ. 2.5 V) and
switching starts at about 80 % of the maximum frequency at the moment pin VDD reaches
the start level.
The start-up state is maintained until VDD reaches the start level (13.5 V), the oscillator is
activated and the converter starts operating.
