APPLICATION NOTES
Premier Magnetics' TSD-1647 Switch Mode Transformer was designed for use with Power Integrations, Inc. PWRTOP222 three terminal off-line PWM switching regulator in the Flyback Buck-Boost circuit configuration. The PWRTOPXXX 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 (85Vac to 265Vac) input high precision 8 watt application circuit utilizing Power
Integrations PWR-TOP222 switching regulator. . The component values listed are intended for reference purposes
only.
