Texas Instruments TPS54383EVM
The TPS54383EVM evaluation module (EVM) is a dual non-synchronous buck converter providing fixed 5.0 V and 3.3 V output at up to 2 A each from a 12 V input bus.
The EVM is designed to start up from a single supply, so no additional bias voltage is required for start-up. The module uses the TPS54383 Dual Non-Synchronous Buck Converter with Integral High-Side FET. TPS54383EVM is designed to use a regulated 12 V (+10%#37; / -20%) bus to produce two regulated power rails, 5.0 V and 3.3 V at up to 2 A of load current each. TPS54383EVM is designed to demonstrate the TPS54383 in a typical 12 V bus system while providing a number of test points to evaluate theperformance of the TPS54383 in a given application. The EVM can be modified to other input or output voltages by changing some of the components.
