Description
The FPF1103/04 are low RDS P-channel MOSFET load
switches of the IntelliMAX™ family. Integrated slew-rate
control prevents inrush current from glitch supply rails
with capacitive loads common in power applications.
The input voltage range operates from 1.2V to 4V to
fulfill today's lowest ultra-portable device supply
requirements. Switch control is by a logic input (ON-pin)
capable of interfacing directly with low-voltage CMOS
control signals and GPIOs in embedded processors.

5 Page Application Information
Input Capacitor
An IntelliMAXTM switch doesn’t require an input
capacitor. To reduce device inrush current effect, a
0.1µF ceramic capacitor, CIN, is recommended close to
the VIN pin. A higher value of CIN can be used to further
reduce the voltage drop experienced as the switch is
turned on into a large capacitive load.
Output Capacitor
An IntelliMAXTM switch works without an output
capacitor. However, if parasitic board inductance forces
VOUT below GND when switching off, a 0.1µF capacitor,
COUT, should be placed between VOUT and GND.
Fall Time
Device output fall time can be calculated based on RC
constant of the external components as follows:
tF = RL × CL × 2.2
(1)
where tF is 90% to 10% fall time, RL is output load, and
CL is output capacitor.
The same equation works for a device with a pull-down
output resistor. RL is replaced by a parallel connected
pull-down and an external output resistor combination,
as follows:
tF
=
RL
RL
× RPD
+ RPD
× CL
× 2.2
(2)
where tF is 90% to 10% fall time, RL is output load,
RPD=65Ω.is output pull-down resistor, and CL is the
output capacitor.
Resistive Output Load
If resistive output load is missing, the IntelliMAXTM
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.
