Dear Support team

I can't find the power consumption information from the LP8752B-Q1's datasheet.

Can you provide the power consumption data of LP8752B-Q1?

Hi,

Page-9 of the datasheet has input supply current consumption details. Is this the information you are looking for ?

Also you can estimate the internal power consumption using the efficiency plots.

Regards,

Murthy

Hi,

Could you tell me how to use this current consumption details to calculate the power consumption ?

Hi Roger,

If you only have know to over all power consumption of the device.
Check on what input/output voltage you are using and what average DC-load is on output.
With that number for example 3.3V input voltage, 1V output voltage and 2A output current efficiency is let's say 85%.
If output power is 1Vx2A=2W and the total input power is 2W/0.85=2.353W. Device power consumption is 2.353W (input power)-2W (output power)=0.353W.

Hope this helps,

Best regards,
