XC9110/XC9111Series
ETR0406-006a
PFM Controlled Step-Up DC/DC Converter / Controller ICs
■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
.

NOTE:
*1: TOREX SD, XBS104S14R-G is used; reverse current IR < 1μA (when reverse voltage VR = 10V is applied), in case of using
selected parts.
*2: "Supply Current 1" is the value when the IC is constantly switching. In actual operation, the oscillator periodically switches, resulting
in lower power consumption. Please refer to Input Current (IIN) under no load condition for the actual current, which is supplied
from the input power supply (VIN).
*3: Lx switch ON resistance can be calculated by (VLx x Rp) / (Vpull - VLx). * Change Vpull so that VLx will become 0.4V.
*4: The Lx limit voltage function becomes stable when VOUT of the XC9110/9111 series is over 2.0V.
*5: EFFI={[output voltage]×(output current)} / [(input voltage)×(input current)]×100
*6: When using VDD and VOUT separately, please set the voltage range of VDD from 1.5V to 10V.
The IC operates from VDD=0.8V, but output voltage and oscillation frequency will be stable when VDD=1.5V or more.
*7: Please be aware of the absolute maximum ratings of the external components.

XC9110/XC9111 Series
■OPERATIONAL EXPLANATION
The XC9110/9111 series are PFM controlled step-up DC/DC converter (A, C and E types) / controller ICs (B, D and F
types), which contain voltage reference source, PFM comparator, duty selector, PFM controlled OSC, VLx Limiter, driver
transistor and so on.
With the XC9110 series, maximum duty ratio is set to 75% (maximum oscillation
frequency=MAXfOSC: 100kHz) making it suitable for use with large current operations. The XC9111 series automatically
switches duty ratio between 56% (MAXfOSC: 180kHz) and 75% (MAXfOSC: 100kHz) when it senses changes in load and
can support both large and small currents.
<Reference Voltage Source (Vref) >
The reference voltage source provides the reference voltage to ensure stable output voltage of the DC/DC converter.
< PFM Comparator >
The PFM comparator compares the feedback voltage divided by the internal split resistors with the internal reference
voltage. When the feedback voltage is higher than the reference voltage, PFM controlled OSC will be stopped. When
the feedback voltage is lower than the reference voltage, the PFM controlled OSC will be operated so that the output
voltage will be stable by sending a signal to the buffer drive circuit and controlling the internal or external driver transistor.
< Duty Selector >
With the XC9111 series, the duty selector automatically switches duty ratio between 56% and 75% when it senses
changes in load and can support both large and small currents.
< PFM Controlled Oscillator >
The PFM controlled OSC determines maximum oscillation frequency. The circuit generates the oscillation frequency of
100kHz at 75% duty and 180kHz at 56%.
< VLx Limiter>
The VLx circuit of the XC9110/9111 A, C and D types detects in-rush current and overcurrent, which flows from the VOUT
pin to the Lx pin during short-circuit. In overcurrent, the driver transistor will be OFF. When the overcurrent state is
eliminated, the IC resumes its normal operation.
<Chip Enable Function>
The chip enable function of the XC9110/9111 C and D types enables the IC to be in shut down mode when a low level
signal is input to the CE pin. During the shut down mode, the current consumption will be reduced to 0.5μA (MAX.).
<Separated VDD/VOUT>
With the separated VDD pin, the XC9110/9111 E and F types can be operated in both low and high voltage.

■NOTES ON USE
1. Please do not exceed the value of stated absolute maximum ratings.
2. The DC/DC converter / controller IC's performance is greatly influenced by not only the ICs' characteristics, but also by
those of the external components. Care must be taken when selecting the external components.
3. The Lx limit voltage function becomes stable when VOUT of the XC9110/9111C series is over 2.0V and the VDD of the
XC9110/9111E series is over 2.0V.
4. Make sure that the PCB GND traces are as thick as possible, as variations in ground potential caused by high ground
currents at the time of switching may result in instability of the IC.
5. Please mount each external component as close to the IC as possible and use thick, short connecting traces to reduce
the circuit impedance.

* The reason for the increase in the "no load input current" figure at Ta=85℃ in the performance characteristics is
because of an increase in the reverse current of the Schottky diode and not because of abnormalities of the IC
