隔离反馈发生器 Isolated Feedback Generator
DESCRIPON
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
