Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9265D291MR-G

The XC9265D291MR-G is an ultra-low power synchronous step-down DC/DC converter designed for high 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 2.9V with an accuracy of ¬±2.0%. The device can deliver an output current of 50mA and features a low quiescent current of 0.50OºA at VOUT of 1.8V, making it suitable for applications requiring extended battery life. This regulator utilizes pulse frequency modulation (PFM) control, which enhances efficiency, especially at low output currents. It includes built-in functions such as under-voltage lockout (UVLO) to prevent operation below a certain voltage and a capacitor discharge feature that quickly brings the output voltage to ground during standby mode. The XC9265D291MR-G is compatible with ceramic capacitors, simplifying the external component requirements to just an inductor and input/output capacitors. The product is suitable for various applications, including wearable devices, smart meters, Bluetooth units, energy harvesting devices, and backup power supply circuits. It is packaged in a SOT-25 format and is compliant with EU RoHS standards.
