A 12-V Input, 5.0-V and 3.3-V Output, 2-A
Non-Synchronous Buck Converter
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.

Non-Synchronous Buck Converter with Integral High-Side FET.
TPS54383EVM is designed to use a regulated 12-V (+10% / -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 the
performance of the TPS54383 in a given application. The EVM can be modified to other input or output
voltages by changing some of the components.
