MAX17502EATB+: FAQ

Was this helpful?

In MAX17502 datasheet it is advised to have a separate analog and power ground and connecting them at a single point on the board. What would go wrong if I use one continuous ground plane?

The rules for the ground planes are very important and should be carefully implemented. Pulsed current are very noisy and they should not interfere with small signal sensing information (e.g FB). Therefore…
In the case with large input capacitor, after the EN and VIN of the MAX17502 is connected, if it is restarted continuously, the second start will take a long time. How do I solve this problem?

With a large input capacitor, even when the input is powered off for 1 second, there will still be a voltage of around 2V at Vin pin of the MAX17502. With Vin connected to EN directly, the voltage at EN…
