TPS3828: impedance between VCC and GND consult

Lin_Charles

Part Number: TPS3828

Hi team,

It is nice to know you here. My customer wants to know the impedance between VCC and GND. I cannot find it in our datasheet. Would you please help share this data with me? Thanks.

Hi Charles,

The effective impedance between VCC and GND will be the supply voltage divide by the ICC current going into the pin.

Hi Ben,

Thank you for your response here. If we do not power up this device, what is the impedance between VCC and GND? This is the data required by the customer. Thanks.

Hi Charles,

We don't have this data but can the customer measure the resistance between VCC and GND with a multimeter? Please have them remove any capacitors that are connected to VDD.
