DESCRIPTION
Output of NDMOS switch
Ground (0V)
Feedback pin for current control loop (connect resistor R1
from this pin to GND for output current I=100mV/ R1)
Enable input (active high to turn on device)
Also used to adjust output current by PWM signal.
Connect to V
Output voltage sense (used for open circuit protection).
Connect to GND if not required.
Input voltage (2.5V to 5.5V). Decouple with capacitor close
to device.
