Hi team,

Could you explain below questions about the reference design and EVM?

1. At the user's guide SLVU960.pdf, how do customer decide the value of capacitors at ILIM1/2 pin?

2. At the reference design PMP4379 TIDRD.pdf, how do customer decide the value of resistors at SS1/2 pin?

Best regards,

Hayashi

Hi Hayashi,

1. For ILIM1/2, the value of capacitors can follow EVM guidance and use 47pF capacitor.

2. For SS1/2 resistor, it is not a must requirement. You can follow the guide in datasheet and user's guide to choose the value of the capacitance which is connected to the SS pin.

Hope it will be helpful.
