Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9281B24E1R-G

The XC9281B24E1R-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 regulator features a quiescent current of 11OºA, ensuring low power consumption, and operates efficiently with up to 90% efficiency at certain conditions. It is available in compact packages, including LGA-6B01 and WLP-5-06, which contribute to reduced PCB space requirements. The XC9281B24E1R-G also includes protection functions such as current limit, soft-start, and under-voltage lockout (UVLO), ensuring reliable operation in various applications. This product is compliant with EU RoHS standards and is suitable for battery-powered devices due to its low profile and efficient design.
