NAME
SON 2x2-8
PGND 1 PWR GND supply pin for the output stage.
This is the switch pin and is connected to the internal MOSFET switches. Connect the
SW 2 OUT
external inductor between this terminal and the output capacitor.
AGND 3 IN Analog GND supply pin for the control circuit.
Feedback pin for the internal regulation loop. Connect the external resistor divider to this pin.
FB 4 IN
In case of fixed output voltage option, connect this pin directly to the output capacitor
This is the enable pin of the device. Pulling this pin to low forces the device into shutdown
EN 5 IN
mode. Pulling this pin to high enables the device. This pin must be terminated
MODE pin = high forces the device to operate in fixed frequency PWM mode. MODE pin =
MODE 6 IN low enables the Power Save Mode with automatic transition from PFM mode to fixed
frequency PWM mode. This pin must be terminated.
Analog V

power supply pin for the output stage.
For good thermal performance, this PAD must be soldered to the land pattern on the pcb.
Power PAD
This PAD should be used as device GND.
