  The UC1901 Simplifies the Problem of Isolated Feedback in Switching Regulators
  PDF, 329 Kb, File published: Sep 5, 1999
  The UC 1901 isolated feedback generator solves 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 that allows a loop error signal to be coupled with a small R. F. transformer or capacitor. This application note discusses the functi
