Function
Enable control input. Force this pin voltage above 1.5V, enables the chip,
and below 0.3V shuts down the device.
Ground
The drains of the internal main and synchronous power MOSFET.
Chip main power supply pin.
Feedback voltage to internal error amplifier, the threshold voltage is 0.1V.

Absolute Maximum Ratings (@TA = +25°C, unless otherwise specified.)
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.
