Pin Function
Supply Voltage (Input): Requires bypass capacitor-to-GND.
Power Ground.
Switch (Output): Internal power MOSFET output switches.
Output after the internal inductor.
Enable (Input): Logic low will shut down the device, reducing the quiescent
current to less than 4µA. Do not leave floating.
Input to the error amplifier. Connect to the external resistor divider network to
see the output voltage. For fixed output voltages connect V
network sets the output voltage).
Feed forward capacitor connected to out sense pin.
Analog ground.
Connect to power ground.
