Isolated Feedback Generator UC1901 UC2901 UC3901 FEATURES • An Amplitude-Modulation System for Transformer Coupling an Isolated Feedback Error Signal • Low-Cost Alternative to Optical Couplers • Internal 1% Reference and Error Amplifier • Internal Carrier Oscillator Usable to 5MHz • Modulator Synchronizable to an External Clock • Loop Status Monitor DESCRIPTION The UC1901 family is designed to solve many of the problems associated with closing a feedback control loop across a voltage isolation boundary. As a stable and reliable alternative to an optical coupler, these devices feature an amplitude modulation system which allows a loop error signal to be coupled with a small RF transformer or capacitor.
