The 171013802 from Wurth Elektronik is a Variable Buck DC-DC Converter that converts an input voltage of 3.5-38 V to an output voltage of 0.85-13 V. It has an efficiency of up to 94% and a current capability of 1 A. This DC-DC converter includes a switching regulator with integrated MOSFETs, a controller, a compensation circuit and a shielded inductor in one package. It uses current mode control to enhance the performance and stability of the power supply. This converter has a constant, selectable switching frequency and offers synchronous operation. It includes an embedded soft-start and incorporates spread spectrum for optimized EMI performance. This RoHS-compliant converter has integrated protection circuitry that guards against thermal overstress with thermal shutdown and protects against electrical damage using overcurrent, output overvoltage, short circuit and undervoltage detection. It is available in a surface-mount package that measures 10 x 6 x 3.1 mm and is ideal for DSPs, FPGAs, MCUs and MPUs supply, I/O interface power supply, point-of-load DC-DC applications, industrial, medical and test and measurement applications.
