DETAILED DESCRIPTION

The

MP62040/MP62041

Power

Distribution

Switch is designed for high-side load switch. The

switch operates from 1.7V to 5.5V nominal input

voltage and can handle up to 2A continuous load.

Enable

The logic pin disables the switch to reduce overall

supply current .Once the EN pin reaches logic

enable threshold, the MP62040/MP62041 is

enabled and the supply current is very small, only

2μA.

APPLICATION INFORMATION

Power-Supply Considerations

Over 10μF capacitor between IN and GND is

recommended. This precaution reduces power-

supply transients that may cause ringing on the

input.

In order to achieve smaller output load transient

ripple, placing a high-value electrolytic capacitor

on the output pin(s) is recommended when the

load is heavy.
