The XC9257B15CMR-G is a synchronous step-down DC/DC converter from Quarktwin Technology Ltd. It is designed to provide a stable output voltage in the range of 0.8V to 3.6V with an accuracy of ±2.0%, and can deliver an output current of up to 1.0A. The device operates with an input voltage range of 2.5V to 5.5V and features selectable oscillation frequencies of 1.2MHz or 6.0MHz, allowing for flexibility in application design. This regulator employs HiSAT-COT control for excellent transient response, with the XC9257 series utilizing PWM control. It includes a soft-start function with a typical turn-on time of 0.3ms, and during standby, it consumes less than 1.0OºA of current. Protection features include thermal shutdown, current limit, and under-voltage lockout (UVLO). The XC9257B15CMR-G is available in SOT-25 and USP-6C packages and is compliant with EU RoHS standards. It is suitable for applications in smartphones, portable devices, and point-of-load systems.
