Part Number: LM76003
Hi there!
On datasheet, it is stated:
When the FB voltage is within the power-good band, +6% above and –7% below the internal reference VREF typically, the PGOOD switch is turned off, and the PGOOD pin voltage is pulled to ground. When the FB is 2% (typical) closer to FB than the PGOOD threshold, the PGOOD switch is turned off, and the pin is pulled up to the voltage connected to the pullup resistor.
I think there's something wrong. Could it be that the following is right?
When the FB voltage is OUTSIDE the power-good band, +6% above and –7% below the internal reference VREF typically, the PGOOD switch is turned ON, and the PGOOD pin voltage is pulled to ground. When the FB is 2% (typical) closer to FB than the PGOOD threshold, the PGOOD switch is turned off, and the pin is pulled up to the voltage connected to the pullup resistor
Or did I understand this pin completely wrong?
Thanks in advance, best regards
