XC9145B33CMR-G

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%@V1×2 2.4V, V0∪7 = 3.3V, |0∪7 = 10|A) 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.
