Pin Name
AME5110AEEVxxx AME5110BEEVADJ
Enable Control Input.
Forcing this pin above 1.5V enables the part. Forcing this
pin below 0.3V shuts down the device. In shutdown, all
functions are disabled drawing <1µA supply current.
Do not leave EN floating.
Ground Pin
Switch Node Connection to Inductor.
This pin connects to the drains of the internal main and
synchronous power MOSFET switches.
Main Supply Pin.
Must be closely decoupled to GND, Pin2, with a 2.2µF or
greater ceramic capactior.
Feedback Pin.
Receives the feedback voltage from an external resistive
divider across the output.
