Amount of time required for output voltage and P-Good pin to output after they fulfill the start-up conditions

8-4 P-Good pin

・

Output state of the converter may be obtained by using P-Good pin (7pin). The pin is an open drain

output. When using the P-Good features, the pin needs to be pulled up by input voltage with

external resistor. (5.5Vmax)

When output voltage (+Sense pin voltage) goes out of the converter’s pre-set range, P-Good pin

becomes SHORT (LOW).

|Output voltage－Set voltage| ≦0.2V typ

However, even if the above conditions are fulfilled, the P-Good pin may decrease to low under the

following circumstances.

At start-up (4ms typ)

Input voltage is less than 3V

Output current is in the state of over current

IC junction temp exceeds 150°C
