I'm reviewing a single component DC converter for the TI SWIFT™ Power Module EVM RoadTest. This article is a review of the efficiency of switching device.     Efficiency According to Specs and Fellow RoadTesters  The datasheet of the TPSM84A21 says shows the efficiency graph. As in the image below, I've also measured with VG open. Feeding a stable 5V to VG improves the efficiency with a few (2 - 4) %. Road Tester fmilburn has measured efficiency on his kit, and pos ...

I'm reviewing a single component DC converter for the TI SWIFT™ Power Module EVM RoadTest. This article is a review of the switching device and the test setup.   Feel free to comment with the tests you'd like to see done with the module.     The Switching Device TPSM84A21  The TPSM84A21 is a hybrid DC to DC Buck converter. All electronics to make it switch are in the package. It doesn't require external inductors or capacitors to work. In the simplest setup, no ot ...
