"In the MP2393 datasheet, the recommended input voltage (VIN) is 19V, but I am using 24V as the input. Which component values will change to accommodate the higher input voltage, and how should I select the appropriate component values for this configuration?
Hi Harshad,
You may refer to the application section of the datasheet for component sizing. To appropriately set the components for your specific application.
If you operating range is not so different from the example circuit provided in the datasheet. Going from 19V to 24V input is not a drastic change. I recommend changing the input caps from a 25V rated to 50V rated capacitors. For output, you can keep the 16V rating.
Refer to eval board BOM.

If I change only the input capacitor to a 50V rating and keep the other components with the same values, will the circuit still provide a stable 3.3V output at 3A? Additionally, I plan to connect one LED after the input capacitor to check if 24V is present. I will also connect another LED at the Vout to confirm that the 3.3V output is functioning correctly. Will this setup allow me to properly verify the voltage levels and ensure the circuit is working as expected?
Aslo give the idea about how to connect LED’S
I have replied to the latest post outlining this. Will add further support there.
