IntelliMAX™ Ultra-Small, Slew-Rate-Controlled Load Switch
Features
Description
1.2 V to 5.5 V Input Voltage Operating Range
The FPF1203 / 03L / 04 / 45 are ultra-s mall integrated
IntelliMA X™ load sw itches w ith integr ated P-channel
sw itch and analog control features. Integrated s lew rate control pr events inr ush current and the resulting
excessive voltage drop on the pow er rail. The input
voltage range operates from 1.2 V to 5.5 V to provide
pow er-disconnect capability for post-regulated pow er
rails in por table and cons umer pr oducts. The low shutoff current allow s pow er designs to meet standby and
off-pow er drain specifications.
Typical RON:
45 mΩ at V IN=5.5 V
55 mΩ at V IN=3.3 V
90 mΩ at V IN=1.8 V
185 mΩ at V IN=1.2 V

The FPF120x are c ontr olled by a logic input ( ON pin)
compatible w ith standar d CMOS GPIO circuitry found
on Field Programmable Gate Array (FPGA) embedded
processors. The FPF120x are available in 0.76 mm x
0.76 mm 4-bump WLCSP.
