APPLICATION NOTES
Premier Magnetic's TSD-1110 Switch Mode Transformer was designed for use with Power Integrations, Inc.
TOP224Y 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%. Premier's TSD-1110
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 20 watt application circuit utilizing Power Integrations TOP224Y
switching regulator in the flyback buck-boost configuration. Proper thermal management of the TOP224Y, VR1
& D3 is required for reliable operation. As with any flyback circuit the output is not intended to be run under a
no load condition. Careful evaluation by the end user is required and should be based on the actual
application & it's associated environmental conditions. The component values listed are intended for
reference purposes only.
