PIN FUNCTIONS
PIN
I/O DESCRIPTION
NAME NO
VIN 3 PWR V
IN
power supply pin.
GND 4 PWR GND supply pin
EN 5 IN 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 2 OUT This is the switch pin and is connected to the internal MOSFET switches. Connect the inductor to this
terminal
FB 6 IN Feedback Pin for the internal regulation loop. Connect this pin directly to the output capacitor.
MODE 1 IN 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.
