Function
No Connected
Bias supply. Chip main power supply pin
The drains of the internal main and synchronous power MOSFET.
GND
Feedback voltage to internal error amplifier, the threshold voltage is 0.6V.
No Connected
Enable control input. Force this pin voltage above 1.5V, enables the chip, and
below 0.3V shuts down t he device.
No Connected
