The XC9259B3FE1R-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%. The device can deliver an output current of up to 1.0A and features selectable oscillation frequencies of 1.2MHz or 6.0MHz, allowing for flexibility in various applications. This regulator employs HiSAT-COT control for excellent transient response and offers multiple control modes, including PWM and PWM/PFM auto-switching. It includes protection features such as thermal shutdown, current limit, and under-voltage lockout (UVLO). The soft-start function enables quick turn-on, typically within 0.3ms. The XC9259B3FE1R-G is packaged in an ultra-small LGA-8B01 form factor, making it suitable for space-constrained designs in mobile devices, Bluetooth headsets, and other portable electronics.
