Function
Pin Name
4 VIN
Chip main power supply pin.
2 GND
Ground
1 EN
Enable Control Input. Force this pin voltage above 1.5V, enables the chip, and below
0.3V shuts down the device.
5 VOUT/FB
VOUT: Output voltage feedback pin, an internal resistive divider divides the output
voltage down for comparison to the internal reference voltage.
FB: Feedback voltage to internal error amplifier, the threshold voltage is 0.6V.
3 SW
The drains of the internal main and synchronous power MOSFET.

These are stress ratings only and functional operation is not implied. Exposure to absolute maximum ratings for prolonged time periods may
affect device reliability. All voltages are with respect to ground.
