Externally programmable current limit should be set at < 5A.
This is the collector input to the power device. The ouput load current is supplied
through this pin.
This pin is the bias supply for the control circuitry. The current flow into this pin will
be approximately 1% of the output current. For the device to regulate, the voltage
on this pin must be at least 1.5V greater than the output voltage, but no less than
VCNTL_MIN.
Ground.
This is the power output of the device.
This is a feedback input.
Enable input. When high, should be less or equal to VCNTL.
