ISOLATED_15_V_DC_DC_CONVERTER

Published:2009/7/7 4:40:00 Author:May | From:SeekIC

In this circuit, a TL431 shunt regulator is used to sense the output voltage. The TL431 drives the LED of a 4N28 optocoupler which provides feedback to the MAX641 while maintaining isolation between the input, + 12 V, and the output, + 15 V. In this circuit, the + 15 V output is fully regulated with respect to both line and load changes.
