PWRTOP249YAI . This series contains all necessary functions for an off-line switched mode control DC power source. These switching regulators provide a very simple solution to off-line designs. The inductors and transformer used with the PWR-TOPXXX are critical to the performance of the circuit. They define the overall efficiency, output power and overall physical size. Below is a universal input (85Vac to 265Vac) input high precision 1215 watt (maximum when all secondary load) a application circuit utilizing Power Integrations PWR-TOP2497 switching regulator. . The component values listed are intended for reference purposes only.
