The XC9257B28CER-G is a synchronous step-down DC/DC converter designed for high efficiency and stable power supply applications. It features a built-in P-channel MOS driver and N-channel MOS switching transistor, allowing for the use of ceramic capacitors. The output voltage is fixed at 2.8V with an accuracy of ¬±2.0%, and it can deliver an output current of up to 1.0A. 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, suitable for various applications. The XC9257B28CER-G employs HiSAT-COT control for excellent transient response and includes features such as thermal shutdown, current limit, soft-start, and under-voltage lockout (UVLO). In standby mode, it consumes less than 1.0OºA, making it suitable for battery-powered devices. The product is available in SOT-25 and USP-6C packages and is compliant with EU RoHS standards. Applications include smartphones, Bluetooth devices, portable game consoles, and wearable technology.
