Function Description (Cont.)

Power Good Indicator

POK is actively held low in shutdown and soft-start status.

In the soft-start process, the POK is an open-drain. When

the soft-start is finished, the POK is released. In normal

operation, the POK window is from 87.5% to 112.5% of

the converter reference voltage. When the output voltage

has to stay within this window, POK signal will become

high after 0.5ms internal delay. When the output voltage

outruns 82.55% or 117.5% of the target voltage, POK sig-

nal will be pulled low immediately. In order to prevent

false POK drop, capacitors need to parallel at the output

to confine the voltage deviation with severe load step

transient.
