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.
