23 Texas Instruments PowerLab TM Search Hundreds of Power Designs in Seconds 23

24 PowerLab at a Glance A library of TI power reference designs that have been built and tested Includes an interactive search tool that allows customers to sort through hundreds of designs Vin, Vout, Iout, topology, application, part number, etc. Each design contains a schematic, bill of material and test report The designs leverage many years of power supply design expertise PowerLab is open to the public on TI s Power Website

25 Selecting a Power Reference Design Select by input-output criteria or part number Select by application or topology Select isolated, non-isolated or AC, DC

26 Let s find a universal input flyback controller Select Flyback 109 Flyback reference designs Table can be further sorted by clicking on any of the headers

27 Refine the list to 90V-300V input range Select input voltage range to 90V-300V 3 Flyback reference designs with 90V to 300V input capability Let s take a look at PMP6570

28 Click PMP6570 and go to reference design folder Brief description Board Photographs Test Results Bill of Material Schematic
