The XC9221C095MR-G is a 16V Input Step-Down DCDC Controller manufactured by Torex Semiconductor. It is a switching controller that allows for the conversion of higher voltage to lower voltage as needed. It is intended for use in automotive applications, as it is able to withstand wide operating temperature range. The controller features a ramp coefficient, over-temperature protection, and an enable feature. It also includes an output feedback, inrush current limit, and multiple protections against overcurrent, over-voltage, under-voltage, and short-circuit conditions.
