.The XC9119D10AMR-G is a Boost Switching Regulator IC manufactured by Torex Semiconductor. This single output IC has positive adjustable 2.5V output voltage and can provide up to 310mA of current. It is housed in a SC-74A, SOT-753 package. It includes internal circuits such as an oscillation control circuit, logic circuits, error amplifier, comparator, and switching devices to provide a boost DC/DC switching regulator. Its features include an operating supply voltage range of 2.2V to 6V, wide operating temperature range from -40°C to 105°C, and a wide output current range of 1mA to 310mA. It is suitable for low voltage and small current step-up applications, such as LCD power supply.
