TPS55386EVM-363 Bill of Materials
The TPS55383EVM-363 evaluation module (EVM) is a dual non-synchronous buck converter providing
fixed 5.0V and 3.3V output at up to 3A 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 TPS55386
600kHz Dual Non-Synchronous Buck Converter with integral high-side FET.

600kHz Dual Non-Synchronous Buck Converter with integral high-side FET.
TPS55386EVM-363 is designed to use a regulated 12V (+10% /–20%) bus to produce two regulated
power rails, 5.0V and 3.3V at up to 3A of load current each. TPS55386EVM-363 is designed to
demonstrate the TPS55386 in a typical 12-V bus system while providing a number of test points to
evaluate the performance of the TPS55386 in a given application. The EVM can be modified to other input
or output voltages by changing some of the components.
