Overview

The TPS54386EVM 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 TPS54386 Dual Non-Synchronous Buck Converter with Integral High-Side FET. TPS54386EVM 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. TPS54386EVM is designed to demonstrate the TPS54386 in a typical 12-V bus system while providing a number of test points to evaluate the performance of the TPS54386 in a given application. The EVM can be modified to other input or output voltages by changing some of the components.

Features
  • 12-V (+10% / -20%) Input Range
  • 5.0-V and 3.3-V Fixed Output Voltage, Adjustable with Resistor Change
