Power Good (PG)
The PG comparator has an open drain output capable of sinking typically 10mA. The PG is only active when
the AP6015 is enable (EN=high). When the AP6015 is disable (EN=low), the PG pin is high impedance.
If the PG pin is connected to the output of the AP6015 with a pull-up resistor, no initial spike occurs and
precautions have to be taken during start-up.
The PG pin becomes active high when the output voltage exceeds typically 92% of its nominal value. Leave
the PG pin unconnected when not used.
