AMC1311-Q1: test problem

Allen Chu

Part Number: AMC1311-Q1

Dear Engineer,

When testing AMC1311BQ, there is a slight discrepancy between the output value and the theoretical calculation. Can you help me analyze it?

Hi Chu,

The first thing I would try is removing C45.

Can you give me some information on the customer and application?

Have you measured the input side (Vin+) with a scope? Does it have the ripple that is seen on the output scope captures you have shared?

Thanks.

Hi Saleh,

Thanks.

Removing C45 is OK.
