Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9235C2KDMR-G

The XC9235C2KDMR-G is a synchronous step-down DC/DC converter capable of delivering an output current of 600mA. It operates within an input voltage range of 2.0V to 6.0V and features a fixed output voltage of 2.75V. 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%. The XC9235C2KDMR-G supports a switching frequency of 1.2MHz and includes features such as PWM control for stable operation, a soft start function, and a built-in under-voltage lockout (UVLO) to protect against low input voltage conditions. It is designed to work with low ESR ceramic capacitors, making it suitable for compact applications. The device is available in a SOT-25 package and is compliant with EU RoHS standards. Applications include mobile devices, Bluetooth devices, and portable gaming consoles.
