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. 1.2 V to 5.5 V Input Voltage Operating Range Typical RON: 45 mΩ at VIN=5.5 V 55 mΩ at VIN=3.3 V 90 mΩ at VIN=1.8 V 185 mΩ at VIN=1.2 V Slew Rate Control with tR: FPF1203/FPF1203l/FPF1204: FPF12045: 2 µs 100 µs 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.
