APPLICATION NOTES
Premier Magnetic's TSD-815 Switch Mode Transformer was designed for use with Power Integrations, Inc. PWR-
TOP201YAI three terminal off-line PWM switching regulator in the Flyback Buck-Boost circuit configuration. This
conversion topology can provide isolated multiple outputs with efficiencies up to 90%. Premier's TSD-815
transformer has been optimized to provide maximum power throughput.
The PWR-TOPXXX series from Power Integrations, Inc. are self contained 100KHz three terminal voltage controlled
PWM switching regulators. 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 high precision 20 watt application circuit utilizing Power Integrations PWR-TOP201
switching regulator in the flyback buck-boost configuration. The component values listed are intended for
reference purposes only. The soft start capacitor Css is optional depending on the specific application. Simpler
topology is possible depending on the line/load regulation required.
