The core of the device is a 80mΩ P-Channel MOSFET and capable of functioning over a wide input operating range of 1.6-4 V. Applications Information FDZ2040L Integrated Load Switch Operation Description Figure 21. Typical Application Input Capacitor To reduce device inrush current effect, a 0.1uF ceramic capacitor, CIN is recommended close to VIN pin. A higher value of CIN can be used to further reduce the voltage drop experienced as the switch is turned on into a large capacitive load. Output Capacitor FDZ2040L switch works without an output capacitor. However, if parasitic board inductance forces Vout below GND when switching off, a 1nF capacitor, COUT, should be placed between Vout and GND. Notes: The intrinsic diode for P-Channel load switch would conduct if VOUT is greater than VIN, by a diode drop Demo Board Layout Figure 22.
