LMQ66430-Q1: Current consumption at no load

Hello

What is your input voltage, output voltage, switching frequency ?

Are you using the fixed Vout or ADJ device ?

Thanks

Input: 9V to 42V DC

Output: 5V

EN pin should not disable that means 5V must be there always and Iq must be less in terms of <15uA

Frequency: any frequency which is suitable to achieve above requirement

Its fixed output voltage device

Hello

We will try to take this data within 1 week.

The MODE pin would be grounded for best low current efficiency.

Thanks

Hi Sudharshana, 

Unfortunately there has been a delay because we did not have the part in stock and needed to order a new one. We hope to receive the part this week and we will update you as soon as it arrives. 

Best,

Hi Sudharshana, 

We received an evaluation module for this device that has a variable output. This evaluation module contains a resistor divider at the output which will lower the efficiency rating.

We have put in an order for another evaluation module  which has a fixed output, and thus, much better efficiency for this test case. 

Nonetheless, we went ahead and graphed current/voltage data for the values you specified in this post and we took the liberty of comparing it to the no-load current data. 

We hope this benefits you and we will record and plot the efficiency data once the new board with the fixed output arrives.
