APPLICATION NOTES
Premier Magnetics TSD-2645 Switch Mode Transformer was designed for use with Power Integrations, Inc. PWRTOP249. Premiers TSD-2645transformer has been optimized to provide maximum power throughput.
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 99 watt application circuit utilizing Power Integrations PWR-TOP249
switching regulator in the flyback buck-boost configuration. The component values listed are intended for
reference purposes only. Properly sized heat sinks for the TOP249Y, D3 & D4 as well as proper thermal management
& board layout are critical requirements for efficient and reliable operation.
