Datasheet Summary
XC9110/XC9111 Series
PFM Controlled Step-Up DC/DC Converter / Controller ICs
ETR0406-008
- GENERAL 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 2.5ΩN-channel driver transistor, the XC9110A/C/E and XC9111A/C/E types provide a step-up operation by using only a coil, a capacitor, and a diode connected externally.
The XC9110/9111B, D and F versions can be used with an external transistor for applications...
