Torex Semiconductor, Ltd. PMIC - Voltage Regulators - DC DC Switching Regulators XC9281B1LE1R-G

The XC9281B1LE1R-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 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. The XC9281B1LE1R-G is packaged in a small LGA-6B01 format, measuring 1.2 x 1.2 x 0.3 mm, which is advantageous for space-constrained designs. Additionally, it includes protection features such as current limit, soft-start, and under-voltage lockout (UVLO). This product is compliant with EU RoHS standards and is suitable for various applications, including smartphones, wireless headsets, and portable gaming devices.
