PFM Controlled Step-Up DC/DC Converter
The XC9111 is a family of PFM controlled step-up DC/DC converter/ controller ICs designed to generate low supply voltage by the combination of PFM control and CMOS structure.The XC9111 has a variable 56% or 75% duty ratio and built-in 2.5Ω N-ch driver transistor.
An external transistor can also be used with some versions within the series for applications which may require larger currents.
A CE pin function is optional allowing for shutdown when the IC is not in use, thereby reducing power consumption to a minimum.
