LM5148-Q1: Load Regulation issue.

Hello,

Please attach your quickstart calculator and your schematic.

Is your output voltage sensing point to the fb resistor located at?

The connection from VOUT to FB should terminate at the VOUT location you want the best regulation at.

Hi Orlando,

Please find the attached document of the schematic, and there are a few adjustments done in the actual circuit to the schematic i am providing so do contact me for further details.

Also I have another query regarding the same IC can we implement a Feedforward Looping according to the application note "SLVAEE0" 'Improving Load Transient Response of DC/DC Converters, Powering Controlled Loads'

Hello,

That link is not working. Please post your email.

Yes you can implement feedforward. We usually use a RC instead of a pure capacitor for better pole zero placement.

Hello Orlando,

Here is my mail ID: 'mahankalin@numerosmotors.com' you can contact me using this mail ID, I also need some more explanation regarding the Concept of the Feedforward looping and how does that work if you could provide me with the necessary documentation related to the topic that would be much helpful. and do contact me for so that i can send you the schematic and get the issue sorted out.

Thank you.
