Anwendungshinweise

  • U-110 1.5 Mhz Current Mode IC Controlled 50-Watt Power Supply
    PDF, 298 Kb, Datei veröffentlicht: Sep 5, 1999
    The UC3825 family of PWM control ICs is optimized for high-frequency switched-mode power-supply applications. This application note describes the development of a 1.5 MHz current-mode IC-controlled 50W power supply. Push-pull topology is used for this DC-to-DC converter application of +48V input to +5V at 10A output. Increases in switching speed and dynamic performance are made possible by the U
