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 core of each device is a 55 m P-channel MOSFET and controller capable of functioning over a wide input operating range of 1.2 to 5.5 V. The FPF1204 / 45 contain a 65 on-chip load resistor for quick output discharge when the switch is turned off. The FPF12045 features a faster VOUT Rise Time of 5 μs. Output Capacitor A 0.1 µF capacitor, COUT, should be placed between the VOUT and GND pins. This capacitor prevents parasitic board inductance from forcing VOUT below GND when the switch is on. CIN greater than COUT is highly recommended. COUT greater than CIN can cause VOUT to exceed VIN when the system supply is removed. This could result in current flow through the body diode from VOUT to VIN. 90% VOUT 90% 10% 10% tR tF 3.3V 50% 50% VON Figure 22. Typical Application 90% Input Capacitor To limit the voltage drop on the input supply caused by transient inrush current when the switch turns on into a discharged load capacitor or short-circuit, a capacitor must be placed between the VIN and GND pins. A 1 µF ceramic capacitor, CIN, placed close to the pins is usually sufficient. Higher-value CIN can be used to reduce the voltage drop in higher-current applications. © 2011 Fairchild Semiconductor Corporation FPF1203 / FPF1203L / FPF1204 / FPF12045 • Rev. 1.2.2 10% VOUT tDON tDOFF Figure 23. Timing Diagram for FPF1203/4/045 Board Layout For best performance, traces should be as short as possible. To be most effective, input and output capacitors should be placed close to the device to minimize the effect of parasitic trace inductance on normal and short-circuit operation. Using wide traces or large copper planes for all pins (VIN, VOUT, ON, and GND) minimizes the parasitic electrical effects and the case-ambient thermal impedance. However, the VOUT pin should not connect directly to the battery source due to the discharge mechanism of the load switch. www.fairchildsemi.com 10 FPF1203 / FPF1203L / FPF1204 / FPF12045 — IntelliMAX™ Ultra-Small, Slew-Rate-Controlled Load Switch Operation and Application Description 0.03 C 2X F E A 0.40 B Ø0.20 Cu Pad A1 0.40 D BALL A1 INDEX AREA Ø0.30 Solder Mask 0.03 C 2X TOP VIEW RECOMMENDED LAND PATTERN (NSMD PAD TYPE) 0.06 C 0.292±0.018 0.539 0.461 0.05 C C E 0.208±0.021 SEATING PLANE SIDE VIEWS D NOTES: A.
