The XCL205C123CR-G is a switching voltage regulator micro DCDC converter manufactured by Torex Semiconductor. It has a maximum output current of 600mA and integrates a 600mA inductor into the package. The built-in architecture includes a controller IC, a MOSFET, a constant frequency oscillator and a band gap reference circuit. It offers over-voltage, under-voltage, over-temperature, and over-current protection. It's suitable for low-power DCDC applications with wide input voltage range from 4.5 V to 28 V. Additionally, other features include soft-start, low ripple noise, and fast transient response.
