OFF_LINE_FLYBACK_REGULATOR

Published:2009/7/3 1:47:00 Author:May | From:SeekIC

Circuit NotesThis circuit uses a low-cost feedback scheme in which the dc voltage developed from the primary-side control winding is sensed by the UC1842 error amplifier. Load regulation is therefore dependent on the coupling between secondary and control windings, and on transformer leakage inductance. For applications requiring better load regulation, a UC1901 Isolated Feedback Generator can be used to directly sense the output voltage.
