DESCRIPTION
This pin will indicate high under this situation: VO reaches 90% of its rating voltage.
Open-drain output.
Chip enable (active-high) / (active-low)
The pin of input voltage.
This pin is for input voltage to control circuit.
No internal connection
Output voltage
When this pin connected to the ground, VOUT will be set by the internal feedback
resistors. Otherwise, if using external feedback resistors to decide the VOUT, VOUT =
0.8(R1+R2)/R2 Volts.
Ground.
