The XC9291A12D1R-G from Torex Semiconductor is a Buck DC-DC Converter that converts an input voltage of 2.5 - 6 V to an output voltage of 0.7 - 3.6 V. It has an output current of 600 mA and power dissipation of less than 760 mW. This buck converter utilizes HiSAT-COT transient response technology that makes it possible to minimize the fluctuation of the output voltage for a load transient condition. It offers fast response and output voltage stability for an instantaneous load fluctuation. This RoHS-compliant converter is available in a surface-mount package that measures 0.88 x 0.96 x 0.33 mm and is ideal for smartphones, mobile phones, wireless earphones, headsets, wearable devices, DSC, Camcorder, portable game consoles, smartcards and various small power sources applications.
