400nA Ultra-Low Quiescent 0.5A PWM/PFM Inductor Built-in Step-up DC/DC Converters
XCL108 series are synchronous step-up DC/DC converters which integrates an inductor with a 200mΩ N-channel driver FET and a 270mΩ synchronous P-channel switching FET built-in.
The ultra-low current consumption of 400nA and PWM/PFM auto-switching control have dramatically improved the efficiency of the output current of 10μA or less, which was difficult to achieve in the past. (85.9%@VIN=2.4V, VOUT=3.3V, IOUT=10μA)
XCL108 series can significantly reduce the power consumption of battery-powered devices which consume a large percentage of power when the system is in standby mode. It contributes to keeping battery life longer and reducing battery size smaller.
