Power Switch 1.5A 4-Pin WLCSP T/R

The FPF1203 is ultra-small integrated IntelliMAX load switches with integrated P-channel switch and analog control features. Integrated slew rate 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 FPF1203 is controlled by a logic input (ON pin) compatible with standard CMOS GPIO circuitry found on Field Programmable Gate Array (FPGA) embedded processors. The FPF1203 is available in 0.76 mm x 0.76 mm 4-bump WLCSP.
