The XC9257A3FEER-G is a synchronous step-down DC/DC converter designed for high efficiency and stable power supply applications. It supports an input voltage range of 2.5V to 5.5V and provides an adjustable output voltage from 0.8V to 3.6V with an accuracy of ±2.0%, in increments of 0.05V. The device can deliver an output current of up to 1.0A and features selectable oscillation frequencies of 1.2MHz or 6.0MHz, catering to various application needs. This regulator employs HiSAT-COT control for excellent transient response, with the XC9257 variant utilizing PWM control. It includes several protection features such as thermal shutdown, current limit, and under-voltage lockout (UVLO). The soft-start function allows for quick turn-on, typically within 0.3ms. The device is compatible with ceramic capacitors and is available in SOT-25 and USP-6C packages. It is suitable for applications in smartphones, Bluetooth devices, portable game consoles, digital cameras, and wearable technology.
