The 171010501 from Wurth Elektronik is a Non-Isolated Buck DC-DC Power Module that steps down 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 4 MHz and an efficiency of up to 96%. This REACH compliant step-down converter consists of a switching regulator IC with integrated MOSFETs, a controller, and a shielded inductor. It maintains high efficiency throughout the output current range by automatically transitioning between operation modes based on the load currents. This RoHS-compliant converter utilizes under-voltage lockout (UVLO), thermal shutdown, and a cycle-by-cycle current limit circuitries to prevent false operation and over-load-related damages. It is available in an LGA package 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.
