The XC9145 is an ultra-low power Step-Up DC/DC Converter. It has a low quiescent current of only 400 nA and maintains high efficiency even at low output current. The PWM/PFM automatic switchover control circuit significantly improves the power conversion efficiency and keeps the output ripple low.
The XC9145 is great for applications where the device will need to be on or in stand-by mode for a significant time as it reduces the power consumption of the battery. This contributes to extending the battery life and reducing the size of battery required. Ideal for application designs such as remote controls, wearable, security systems and IoT.
