Functional Description

The TLE 4305 G is specifically designed to control the output voltage and the output

current of a switch mode power supply.

Independent compensation networks for the voltage- and for the current-loop can be

realized by external circuitry.

The device contains a high accuracy bandgap reference voltage, two operational trans

conductance amplifier (OTA), an opto-coupler driver output stage and an high-voltage

bias circuit.

The device is based on Infineons double isolated power line technology DOPL which

allows to produce high precision bipolar voltage regulators with breakdown voltages up

to 45 V.
