Application Information
Input Capacitor
Fall Time
An IntelliMAX
TM
switch doesn’t require an input
Device output fall time can be calculated based on RC
An IntelliMAX
switch works without an output
t F =
R L × R PD
× C L × 2 . 2 (2)
If resistive output load is missing, the IntelliMAX
capacitor. To reduce device inrush current effect, a
0.1μF ceramic capacitor, C IN , is recommended close to
the VIN pin. A higher value of C IN can be used to further
reduce the voltage drop experienced as the switch is
turned on into a large capacitive load.
Output Capacitor
TM
capacitor. However, if parasitic board inductance forces
V OUT below GND when switching off, a 0.1μF capacitor,
C OUT , should be placed between V OUT and GND.

constant of the external components as follows:
t F = R L × C L × 2 . 2 (1)
where t F is 90% to 10% fall time, R L is output load, and
C L is output capacitor.
The same equation works for a device with a pull-down
output resistor. R L is replaced by a parallel connected
pull-down and an external output resistor combination,
as follows:
R L + R PD
where t F is 90% to 10% fall time, R L is output load,
R PD =65 Ω .is output pull-down resistor, and C L is the
output capacitor.
Resistive Output Load
TM
switch without a pull-down output resistor is not
discharging the output voltage. Output voltage drop
depends, in that case, mainly on external device leaks.
