Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9265B3214R-G

The XC9265B3214R-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 3.2V 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 1.8V output, making it suitable for applications requiring extended battery life. This regulator employs pulse frequency modulation (PFM) control, which enhances efficiency, particularly at low output currents. The XC9265B3214R-G includes built-in functions such as under-voltage lockout (UVLO) to prevent operation below a specified voltage and a CL discharge function that quickly discharges the output capacitor during standby mode. It 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 portable game consoles. It operates within a temperature range of -40¬8C to 85¬8C and is available in a compact SOT-25 package, making it a versatile choice for space-constrained designs.
