PWRGD - Power Good Signal
The power good signal will be asserted, driven high, by the converter to indicate that the output is
valid. If any of the outputs fails the specified DC voltage regulation limits or the output is below
90% of the nominal voltage, then the PWRGD signal will be driven low.
The output is an open collector/drain. It is capable of driving the output below 0.4V with a load of
4mA.
PWRGD_SET - Power Good Signal Levelset
The section sets the Power Good signal levels with a single resistor connected between the
PWRGD_SET (Pin9) and Ground (Pin7). Note fault condition is Low signal on PWRGD_SET.
