Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9235C23CMR-G

The XC9235C23CMR-G is a synchronous step-down DC/DC converter designed to provide a stable output voltage with a maximum output current of 600mA. It operates within an input voltage range of 2.0V to 6.0V and features a fixed output voltage of 2.3V. The device incorporates a built-in P-channel MOS driver transistor with a resistance of 0.42Oc and an N-channel MOS switching transistor with a resistance of 0.52Oc, allowing for high efficiency, typically around 92%. This regulator supports both PWM control and automatic PWM/PFM switching modes, ensuring optimal performance across varying load conditions. It includes features such as a soft start function, current limiting, and an under-voltage lockout (UVLO) function to enhance reliability. The XC9235C23CMR-G is compatible with low ESR ceramic capacitors and is available in multiple package options, including SOT-25. Applications include mobile devices, Bluetooth devices, and portable gaming consoles, making it suitable for a wide range of electronic projects.
