TPS65642A: What's value of resistance between VGH and VGHM

Part Number: TPS65642A

Hi Team,

My customer wants to know the value of resistance between VGH and VGHM to select Vcap on VGH. In there evaluation, they would like to change Vcap on it, based on time constant.

Hello Naoki-san,

On page 6 of the datasheet, you can find the following information:

So the typical on resistance is 12 ohm, worst case is 25 ohm.

Please do not forget that the output capacitance on the VGH boost converter is as well part of the stability of the converter. Please stay within the recommended operating range.

Best regards,
Brigitte
