Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9281B0LE0R-G

The XC9281B0LE0R-G is a synchronous rectification DC/DC converter designed for step-down applications, capable of delivering up to 600mA output current. It operates within an input voltage range of 2.5V to 5.5V and offers output voltage options from 0.7V to 3.6V with specified accuracy. The device utilizes HiSAT-COT control technology, which enhances transient response and minimizes output voltage fluctuations during load changes, making it suitable for applications requiring stable power supply, such as mobile devices and wearables. The XC9281B0LE0R-G features a quiescent current of 11OºA, ensuring low power consumption, and operates efficiently with up to 90% efficiency at certain conditions. It supports high-frequency operation with oscillation frequencies of 4MHz or 6MHz, allowing for the use of compact external components, including a 1.0 x 0.5 mm inductor and a 0.6 x 0.3 mm ceramic capacitor, which contribute to a reduced mounting area. The device is packaged in a compact LGA-6B01 or WLP-5-06 format, compliant with EU RoHS standards. This product is particularly well-suited for battery-powered applications and environments where space is limited, but it is noted that the XC9281/XC9282 series is not recommended for new designs.
