Overview
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 combination of PFM control and CMOS structure.
The series is ideal for 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 versions can be used with an external transistor for applications requiring larger currents.
Output voltage is internally programmable in a range from 1.
5V to 7.
0V in increments of 0.
1V (accuracy: ± 2.
5%).
Maximum oscillation frequency is set to 100kHz for XC9110/9111 series.
(At light loads, it is set to 180kHz for the XC9111 series.
) Options include products equipped with a CE pin (C and D versions) that allows the IC to be shut down thereby reducing supply current and with separated VDD/VOUT pins (E and F versions) to separate the power supply block and the output voltage detect block.
With the XC9110 series, maximum duty cycle is set to 75% (VDD=3.
3V) making it suitable for use with large current operations.
The XC9111 series automatically switches duty ratio between 56% & 75% (VDD=3.
3V) when it senses changes in load to drop output ripple voltage and can support both large and small currents.
The external transistor types (B/D/F types) can be provided for applications, which require larger currents.
