The 171010502 from Wurth Elektronik is a Non-Isolated Buck DC-DC Converter that steps down from an input voltage of 2.5 - 5.5 V to an output voltage of 0.8 - 5.5 V. This buck converter has an output current of up to 1 A. It has a switching frequency of fewer than 4.4 MHz and an efficiency of up to 96%. This REACH-compliant converter consists of a controller, a shielded inductor, and a switching regulator IC with integrated MOSFETs.

This RoHS-compliant converter integrates under-voltage lockout (UVLO), thermal shutdown, cycle-by-cycle current limit, and over-temperature protection circuitries to avoid false operation and over-load-related damages. It is available in a module that measures 3.2 x 2.5 x 1.55 mm and is ideal for a general point of load power supply for low power systems, replacement of linear regulators, DSP and FPGA power supply auxiliary voltages, portable instruments, and battery-powered equipment applications.
