XC9111E, XC9110, PFM Controlled Step-Up DC/DC Converter/Controller

XC9110/XC9111 Series PFM Controlled Step-Up DC/DC Converter / Controller ICs ETR0406-008 *GENERAL DESCRIPTION The XC9110/9111 series is a group

Features

* Input Voltage Range : operating hold voltage 0.7V~10.0V Start-up voltage 0.9V~10.0V Output Voltage Range : 1.5V~7.0V in 0.1V increments Output Accuracy : ±2.5% Max Oscillation Frequency : 100 kHz ±15% 180 kHz (at 56% duty of XC9111) Built-in Switch Types : A/C/E type N-ch FET On-Resista

Applications

* where a longer battery life is needed such as in portable communication 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 version
