Hi,

I'm trying to calculate the Power dissipation of the ADP5052. Formulas for BUCK converters give Ploss = Pcond + Psw + Ptran.

For Psw there are two parameters Cgate_HS and Cgate_LS given to be a capacitance (so unit is pF ? )

The datasheet doesn't mention this parameter anywhere I guess. What is the value of this parameters ?

Thanks

Stephane

Hello, Stephane.

Good day! To compute for the power dissipation of ADP5052, I suggest you use the corresponding tool which can be downloaded from this link.

http://download.analog.com/PMP/ADP505x_BuckDesigner.zip

Once you have extracted the Excel file, click "Enter Inputs" and then specify the required parameters. Lastly, click "Submit/Run" and then browse through the sheet for the calculation results. Each channel has loss and component stress calculations along with the other calculated parameters.

Please let me know what else we can help you on.

Thanks and regards,
