APPLICATION NOTES
Premier Magnetics' TSD-1943 Switch Mode Transformer was designed for use with Power Integrations, Inc. TOP247Y
off-line PWM switching regulator in the Flyback Buck-Boost circuit configuration. This conversion topology can
provide isolated multiple outputs with efficiencies up to 82%. Premiers' TSD-1943 transformer has been optimized
to provide maximum power.
The PWR-TOPXXX series from Power Integrations, Inc. are self contained 132KHz 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 62.5 watt application circuit utilizing Power Integrations TOP247Y switching
regulator in the flyback buck-boost configuration. The component values listed are intended for reference
purposes only. Properly sized heat sinks for the TOP2XX & D3 as well as proper thermal management of the
clamp network are critical requirements for efficient and reliable operation.
