Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9265B18B4R-G

The XC9265B18B4R-G is an ultra-low power synchronous step-down DC/DC converter designed for efficiency in battery-operated devices. It operates within an input voltage range of 2.0V to 6.0V and provides a fixed output voltage of 1.8V with an output current capability of 50mA. The device features a low quiescent current of 0.50OºA, making it suitable for applications requiring long battery life. The converter utilizes pulse frequency modulation (PFM) control, which enhances efficiency during low load conditions. It includes built-in functions such as under-voltage lockout (UVLO) to prevent operation below a specified voltage and a CL discharge function to quickly restore output voltage to ground level during standby. The XC9265B18B4R-G is compatible with ceramic capacitors, simplifying external component requirements to just an inductor and input/output capacitors. This product is suitable for various applications, including wearable devices, smart meters, Bluetooth units, and portable game consoles, and operates within an ambient temperature range of -40°C to 85°C. The XC9265B18B4R-G is also compliant with EU RoHS standards, ensuring it is environmentally friendly.
