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.

●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
