  • U-160 Simple Circuit Modifications Enhance Optocoupler Performance
    PDF, 240 Kb, Archivo publicado: sept 5, 1999
    The optocoupler is often used in pulse-width-modulated power converters to transmit an error signal across an isolation boundary. This error signal is used on the primary side to close the control loop. This application note describes a typical optocoupler feedback scheme using the UC3965 Precision Reference with Low-Offset Error Amplifier and a Siemens Optoelectronics IL207 optocoupler. The discu
  • U-128 The UC3823AB and UC3825AB Enhanced Generation of PWM Controllers
    PDF, 204 Kb, Archivo publicado: sept 5, 1999
    The UC3823A and B and the UC3825A and B family of PWM control ICs are improved versions of the standard UC3823 & UC3825 family. This application note describes the enhancements incorporated in four new PWM control ICs: the UC3823A UC3823B UC3825A and UC3825B. Based on the industry standard UC3823 and UC3825 controllers this advanced generation features several key improvements in protection and
