Function
Enable pin for the IC. Drive this pin to high to enable the part, low to disable
Power Ground. The ground of internal power NMOS. Bypass with a 22μF
ceramic capacitor to VIN
Analog Ground. To keep this ground free from noise by connecting a 10nF
ceramic capacitor to VIN. Do not short his pin to PGND directly in PCB,
but through a PCB trace to connect the 2 GND together.
Feedback Input. Connect an external resistor divider from the output to
FB and GND to set the output to a voltage between 0.45V and VIN
Output voltage sense pin, to be connected to the output node of regulator.
Not connected. Please do leave this pin float.
Inductor Connection. Connect an 1uH inductor Between SW and the
regulator output.
Supply Voltage. Bypass with a 22μF ceramic capacitor to PGND and 10nF
to AGND.
