Ultra-Low Power PWM/PFM Synchronous Step-Up DC/DC Converter
The XC9145 series is a synchronous step-up DC/DC converter 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 combine to dramatically improve efficiency at load current levels of 10µA or less (89.9%@VIN=2.4V, VOUT=3.3v, IOUT=10µA).
Output voltage can be set from 3.0V ~ 5.5V (±2%) in 0.1V increments and the XC9145 can support up to 430mA IOUT @ VOUT=5.0V, VBAT=3.3V. Start-up voltage is 1.6V but the XC9145 can then operate down as low as 0.65V in operation.
The 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.
