GND 6 PWR GND supply pin
This is the enable pin of the device. Pulling this pin to low forces the device into shutdown mode. Pulling
EN 4 I
this pin to high enables the device. This pin must be terminated.
This is the switch pin and is connected to the internal MOSFET switches. Connect the external inductor
SW 1 OUT
between this terminal and the output capacitor.
Feedback Pin for the internal regulation loop. Connect the external resistor divider to this pin. In case of
FB 3 I
fixed output voltage option, connect this pin directly to the output capacitor
MODE pin = high forces the device to operate in fixed-frequency PWM mode. Mode pin = low enables
MODE 2 I
the Power Save Mode with automatic transition from PFM mode to fixed-frequency PWM mode.
