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 V

OUT

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% (V

=3.3V) making it suitable for use with large

current operations. The XC9111 series automatically switches duty ratio between 56% & 75% (V

=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.
