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.
