FPF1203 / FPF1203L / FPF1204 / FPF12045
IntelliMAX™ Ultra-Small, Slew-Rate-Controlled Load Switch
Features
Description


The FPF1203 / 03L / 04 / 45 are ultra-small integrated
IntelliMAX™ load switches with integrated P-channel
switch and analog control features. Integrated slewrate control prevents inrush current and the resulting
excessive voltage drop on the power rail. The input
voltage range operates from 1.2 V to 5.5 V to provide
power-disconnect capability for post-regulated power
rails in portable and consumer products. The low shutoff current allows power designs to meet standby and
off-power drain specifications.

The FPF120x are controlled by a logic input (ON pin)
compatible with standard 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.
