Beschreibung
- TPS54291EVM-431 evaluation module (EVM) is a dual synchronous buck converter providing fixed 3.3V and 1.2V outputs at up to 1.5A and 2.5A respectively from a 12V bus. The EVM is designed to start-up from a single supply, so no additional bias voltages are require for start-up. The module uses the TPS54291 600kHz Dual Synchronous Buck Converter with integrated MOSETs. TPS54291EVM-431 is designed to use a regulated 12V (+10% /20%) bus to produce two regulated power rails, 3.3V at 1.5A and 1.2V at 2.5A. TPS54291EVM-431 is designed to demonstrate the TPS54291 in a typical 12-V bus system while providing a number of test points to evaluate the performance of the TPS54291 in a given application. The EVM can be modified to other output voltages by changing some of the components
