TNY255 off-line switchmode regulator in the Flyback Buck-Boost circuit configuration. This conversion topology will provide an isolated output with efficiencies up to 90%. Premiers' PNY-05015 transformer has been optimized to provide maximum power throughput. The TNYXXX series from Power Integrations, Inc. are self contained 40 or 130KHz 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 low power designs less than 5W and off high volate DC Bus designs less than 10W. The inductors and transformer used with the TNYXXX 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 7.5 watt application circuit utilizing Power Integrations TNY255 switching regulator in the flyback buck-boost configuration. The component values listed are intended for reference purposes only. Proper thermal managment of the TNY255 & D1 is required for reliable operation. The TNY255 should be mounted on > 0.75 in2, 2oz copper clad to provide a proper heat sink starting point for evaluation. 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.
