NOTE:
*1: TOREX SD, XB01SB04A2BR is used; reverse current IR < 1
μ
A (when reverse voltage V
R
= 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 (I
IN
) under no load condition for the actual current, which is supplied
from the input power supply (V
IN
).
*3: Lx switch ON resistance can be calculated by (V
Lx
x Rp) / (Vpull - V
Lx
). * Change Vpull so that V
Lx
will become 0.4V.
*4: The Lx limit voltage function becomes stable when V
OUT
of the XC9110/9111 series is over 2.0V.
*5: EFFI={[output voltage]

*6: When using V
DD
and V
OUT
separately, please set the voltage range of V
DD
from 1.5V to 10V.
The IC operates from V
DD
=0.8V, but output voltage and oscillation frequency will be stable when V
DD
=1.5V or more.
*7: Please be aware of the absolute maximum ratings of the external components.
