APPLICATION NOTES
Premier Magnetics' TSD-1390 Switch Mode Transformer was designed for use with Power Integrations TOP226Y
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-1390 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 55 watt application circuit utilizing Power Integrations TOP226 switching
regulator in the flyback buck-boost configuration. The component values listed are intended for reference
purposes only. A properly sized heat sink for the TOP226Y, D3 & D4 are required for efficient and reliable
operation.
