step-up operation by using only an inductor, a
capacitor, and a diode connected externally.
The IXD2110/111B, D, and F versions can be used
with an external transistor for applications requiring
larger currents.
Output voltage is internally programmed in a range
from 1.5V to 7.0V in increments of 0.1V (accuracy
± 2.5%).
Maximum oscillation frequency is set to 100 kHz for
IXD2110/111 series. (At light loads, it is set to
180 kHz for the IXD2111 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

pins (E and F versions) to separate the
power supply block and the output voltage detect
block.
With the IXD2110 series, maximum duty cycle is set
to 75% (V
DD
= 3.3 V) making it suitable for use with
large current operations. The IXD2111 series
automatically switches duty ratio between 56% &
75% (V
DD
= 3.3 V) to drop output ripple voltage, when
it senses changes in load, It can support both large
and small currents.
The external transistor types (B/D/F types) designed
for applications, which require larger currents.

DESCRIPTION
The IXD2110/IXD2111 series is a group of PFM step-
up DC/DC converter/controller ICs, designed to
generate low supply voltage. The series is ideal for
applications where a longer battery life is needed
such as in portable communication equipment. With a
built-in 2.5
N-channel driver transistor, the
IXD2110A/C/E and IXD2111A/C/E types provide a
