The MAX17501 RESET pin is an open drain output used to indicate whether the output voltage is within the expected value. This pin is usually pulled up to Vout (output voltage node) with a 10k ohm resistor…
As for the MAX17501's soft start capacitor, its value should be:
CSS ≥ 6 x Coutput x VOUT
If the output capacitor is increased with the CSS value at its default state, the device will be shut down…
