DESCRIPTION
V IN power supply pin.
GND supply pin
This is the enable pin of the device. Pulling this pin to low forces the device into shutdown mode. Pulling
this pin to high enables the device. This pin must be terminated.
SW

OUT
This is the switch pin and is connected to the internal MOSFET switches. Connect the inductor to this
terminal

IN
IN
Feedback Pin for the internal regulation loop. Connect this pin directly to the output capacitor.
MODE pin = high forces the device to operate in PWM mode. Mode = low enables the Power Save Mode
with automatic transition from PFM (Pulse frequency mode) to PWM (pulse width modulation) mode.
