XC9110 Description
The XC9110/9111 series is a group of PFM controlled step-up DC/DC converter/controller ICs designed to generate low supply voltage by the bination of PFM control and CMOS structure. The series is ideal for applications where a longer battery life is needed such as in portable munication equipment. With a built-in 2.5Ω N-channel driver transistor, the XC9110A/C/E and XC9111A/C/E types provide a step-up operation by...
