XC9145 Series

400nA Ultra-Low Quiescent, 0.8A, PWM/PFM Step-up DC/DC Converters

XC9145 series are synchronous step-up DC/DC converters 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. (89.9%@VIN=2.4V, VOUT=3.3V, IOUT=10μA)

XC9145 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.
