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.
