LM5066: LM5066I

6351228

Part Number: LM5066

Tool/software:

Dears,

LM5066 Pin monitoring accuracy is +/- 4.5%, and LM5066I is +/-2.5%.

According to our experiment result, the accuracy of light load is more than the specification +/-4.5 or +/-2.5, and the Pin accuracy might be more than 10% if delta Vsense is less 3mV.

the delta Vsense is equal to Vsens+ - Vsense-.

Could you provide with the curve of the accuracy vs delta Vsense?

which factor is the major part to let accuracy worse?

Thanks.

Hi,

Let me check and get back on this.

Hi Kunal,

Thanks, please help update the information after you get the data

Hi,

We don't have that data available. At the lower load current, the accuracy is expected to degrade, This is because of offset in the current sense amplifier.

Dear Kunal,

Could you provide with the offset range?

Due to current sense amplifier offset, the Pin and Iin accuracy in the light load condition would be out of the spec(LM5066 +/-4.5% and LM5066I +/-2.5%). Right?

if yes, will the data sheet of LM5066 and LM5066I be updated about the relationship of Pin/Iin accuracy and the delta Vsense?

Thanks.
