Application Notes

  • Qualifier TJ = TA Defined
    PDF, 22 Kb, File published: Nov 3, 2010
    In the header of most datasheet specification tables there is a qualifier for the tests defined in the table,(TA = TJ, unless otherwise stated). Specifically, these tests are valid for the device as long as the junctiontemperature remains within the specified limits for that device.
  • U-110 1.5 Mhz Current Mode IC Controlled 50-Watt Power Supply
    PDF, 298 Kb, File published: 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
