PRODUCTION DATA
The Power Good pins (PGOOD1, PGOOD2) are open-drain outputs that require a pullup resistor of 1 kΩ to 100 kΩ to a voltage source of 5.5 V or less to indicate the output voltage is within the PGOOD range. The BP5 output can be used as the pullup voltage source. The PGOOD detection is activated after soft start is completed. When the output voltage is within a range of ±10% of the target, the PGOOD goes high after a 50-µs internal delay. During operation, if the output voltage falls outside of ±10% of target voltage, PGOOD is pulled low after a 10-µs delay. The PGOOD feature is active while the voltage at the VIN pin is either equal to or greater than 1.5 V.
