Detailed Description

6.3.2

Generic Powergood Window Comparator with Open-Drain Output

The generic powergood comparator monitors the output voltage to ensure it is within ±10% of the nominal

target voltage there is a 30-µs deglitch on both rising and falling edges of all comparators (converter,

controller, comparators). The open-drain output requires an external pull-up resistor - typically in the 100-

kΩ range. Open-Drain outputs can be combined to create an "AND" logic function.
