The 173950336 from Wurth Elektronik is a Non-Isolated Buck DC-to-DC Converter that steps down an input voltage from 4.75-36 V to an output voltage of 3.3 V. This converter has an output current of 0.5 A. It provides a switching frequency of 710 MHz and has an efficiency of up to 92%. This step-down converter consists of a controller IC, inductor and capacitor. It also uses external input and output capacitors along with an input filter to deliver an optimum performance. This RoHS and REACH compliant converter provide an internal soft-start and current mode control feature to protect the circuit against over-current and over-voltage related damages. It is available in a through-hole package that measures 11.6 x 7.55 x 10.16 mm and is ideal for interface and microcontroller supplies, replacement for linear regulators, general purpose and point-of-load DC-DC applications.
