  • The UC1901 Simplifies the Problem of Isolated Feedback in Switching Regulators
    PDF, 329 Kb, Datei veröffentlicht: 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
  • DN-19 A Simple Isolation Amplifier Using the UC1901
    PDF, 112 Kb, Datei veröffentlicht: Sep 5, 1999
    The UC1901 Isolated Feedback Generator has other applications besides providing isolated feedback in switching power supplies. This IC's amplitude modulation system and error amplifier can implement an isolation amplifier characterized by (1) good signal linearity (2) wide bandwidth (3) high isolation capability and (4) low cost. Isolation amplifiers of this type are in switching power supplies
  • DN-33 Optocoupler Feedback Drive Techniques Using the UC3901 and UC3903
    PDF, 45 Kb, Datei veröffentlicht: Sep 5, 1999
    A variety of low-cost supervisory ICs contain the required building blocks for the more demanding optocoupler feedback drive applications. Initially developed to address other specific power supply tasks several control ICs excel in the role as precision optocoupler control and drivers. This design note describes a basic optocoupler driver circuit and also a more advanced optocoupler drive circ
