High Efficiency Step-Down Low Power DC-DC Converter
Application Information (Continued)
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.
