APPLICATION NOTES
Premier Magnetic's TSD-1476 Switch Mode Transformer was designed for use with Power Integrations, Inc. PWRTOP202YAI 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-1476
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 Dual Output 17 watt application circuit utilizing Power Integrations PWR-TOP202
switching regulator in the flyback buck-boost configuration. The component values listed are intended for
reference purposes only.
