APPLICATION NOTES
Premier Magnetics' TSD-877 Switch Mode Transformer was designed for use with Power Integrations, Inc. PWRTOP204YAI three terminal off-line PWM switching regulator in the Flyback Buck-Boost circuit configuration. 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 (85Vac to 265Vac) input high precision 15 watt application circuit utilizing Power
Integrations PWR-TOP204 switching regulator. This circuit provides three precision outputs. The "MAIN" output of
secondary #2B is optically fed back to the PWR-TOP201 controller to close the voltage feedback loop.
Secondary #1 is fed into a linear regulator to provide a high precision output. The component values listed are
intended for reference purposes only.
