Würth Elektronik offers tiny step-down DC-DC converter

 MagI3C-VDMM (Variable Step-Down Micro Module) is a small LGA-6EP package with a size of 3.2 x 2.5 x 1.6mm. The input voltage range of the buck converter is VIN from 2.75 to 5.5Vdc. As a result, the DC-DC converter can operate on a 5V or 3.3V bus. The integrated power module for inductors and capacitors has a VOUT range of 0.6 to 5.5V. This module is designed to replace linear controllers and can provide output currents up to 600mA. Power modules are suitable for powering interfaces, microcontrollers, microprocessors, DSPs and FPGAs.
