APPLICATION NOTES
Premier Magnetics' TSD-974 Switch Mode Transformer was designed for use with Power Integrations, Inc. PWRTOP104YAI 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%. Premiers' TSD-974
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 dc/dc and direct off-line
switched mode DC power sources. These switching regulators provide a very simple solution to flyback 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 -48Vdc input precision 16W watt application circuit utilizing Power Integrations PWR-TOP104YAI
switching regulator in the flyback buck-boost configuration. If the 118V output is to be run unload a clamp
resistor (R5) should be added to prevent possible destructive voltage runaway. The component values listed
are intended for reference purposes only.
