1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ(MAX), the junction-to-
ambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowable continuous power dissipation at

calculated
by
PD(MAX)=(TJ(MAX)-TA)/θJA. Exceeding the maximum
allowable power dissipation will cause excessive die
temperature, and the regulator will go into thermal shutdown.
Internal thermal shutdown circuitry protects the device from
permanent damage.

FUNCTION BLOCK DIAGRAM
Figure 2 ― Functional Block Diagram
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.
