APPLICATION NOTES
Premier Magnetics' TSD-1439 Switch Mode Transformer was designed for use with Power Integrations, Inc.
TOP223 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-1439
transformer has been optimized to provide maximum power throughput.
The 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 4 watt application circuit utilizing Power Integrations TOP221Y switching
regulator in the flyback buck-boost configuration. The component values listed are intended for reference
purposes only. Proper thermal managment of the TOP221, VR1 & D3 is required for reliable operation. The
TOP221Y should be mounted on > 0.75 in 2 , 2oz copper clad to provide a proper heat sink starting point for
evaluation. As with any flyback circuit the output is not intended to be run under a no load condition. The
component values listed are intended for reference purposes only. Careful evaluation by the end user is
required and should be based on the actual application & it's associated environmental conditions.
