LM5067: LM5067-Load transient test

Part Number: LM5067

Hi Team

We are planning to Load transient test with minimum and maximum load to validate LM5067. How can we do this? Can anyone suggest?

Hi Srikanth,

Thanks for reaching out. You can do using an electronic load or a resistive load with a switching option. I am not able to understand what exactly you are looking for.

Hi Avishek

Thanks for your response. I have shown my schematics in below screenshot. We want to switch the load from minimum load(1A) requirement to maximum load requirement (3A) in 10ms duration. 10ms min load and 10ms max load. Do I have the sufficient capacitance for the required transient response?

Hi Srikanth,

I will get back to you tomorrow.

Hi Srikanth,

It is not like the switching regulators. As long as the load current is less than the current limit threshold, the input supply will provide that load current. The output capacitor doesn't have much contribution on this load transient unlike the switching regulators. Please test it and capture the input & output voltages and load current waveforms.
