The 171023802 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 delivers an output current of less than 2 A and has an efficiency of up to 94%. This converter integrates a switching regulator with built-in MOSFETs, a controller, compensation components, and a shielded inductor. It supports a constant, selectable PWM switching frequency over its entire operation to optimize output ripple for sensitive and precise applications. This DC-DC converter has built-in protection against electrical damage with its overcurrent, output overvoltage, short circuit, and undervoltage detection features. It has a power-good indicator and includes a thermal shutdown facility to withstand thermal overstress. This RoHS-compliant DC-DC converter is available in a surface-mount package that measures 10 x 6 x 3.1 mm and is suitable for industrial, medical, test and measurement, DSPs, FPGAs, MCUs and MPUs supply, I/O interface power supply and point-of-load DC-DC applications.
