    The TPS548A20EVM-PWR737 evaluation module (EVM) uses the TPS548A20. The TPS548A20 is a D-CAP3™ mode, 15A synchronous buck converter with integrated MOSFETs. It provides a fixed 1.2V output at up to 15A from a 12V input bus.

    The TPS548A20EVM-737 is designed for a regulated 12-V bus to produce a regulated 1.2-V output at up to 15 A of load current. The TPS548A20EVM-737 is designed to demonstrate the TPS548A20 device in a typical low-voltage application while providing a number of test points to evaluate the performance of the TPS548A20 device.

    The TPS548A20 is a small-sized, synchronous buck converter with an adaptive on-time D-CAP3 control mode. The device offers ease-of-use and low bill-of-material count for space-conscious power systems.
