Description
XC9110/XC9111 Series PFM Controlled Step-Up DC/DC Converter / Controller ICs ETR0406-008 *GENERAL .
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 combination.
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.
