The XC9258A21CER-G is a synchronous step-down DC/DC converter designed for high efficiency and stable power supply applications. It features an output current capability of 1.0A and an output voltage range from 0.8V to 3.6V, adjustable in increments of 0.05V with an accuracy of ±2.0%. The device operates within an input voltage range of 2.5V to 5.5V and offers selectable oscillation frequencies of 1.2MHz or 6.0MHz, making it suitable for various applications. This regulator employs automatic PWM/PFM switching control, which enhances efficiency across a wide load range, from light to heavy loads. It includes several protection features such as thermal shutdown, current limit, and under-voltage lockout (UVLO), ensuring reliable operation. The XC9258A21CER-G also incorporates a soft-start function with a typical time of 0.3ms, minimizing inrush current during startup. It is compatible with ceramic capacitors and is available in SOT-25 and USP-6C packages. The product is compliant with EU RoHS standards, making it environmentally friendly.
