The MxL7704 offers two configurable Power Good outputs, PG1 and PG2. Each PGOOD flag can be monitored and assigned via the 400 kHz I²C interface. Two sequencing and PGOOD routing scenarios are shown. In the first example, PG1 goes high at approximately 7 ms (2 ms after Buck 4 reached 90% of its final value). PG2 is assigned to the LDO and to Bucks 1, 2, and 3. PG2 goes high 2 ms after the last of those rails, 1, reaches >90% of its final value, which in this case is Buck 1.
