Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
HI
The reason is the ripple current is increasing and out of the capacitor's RMS current rating.
below is my suggestion:
1. paralleling low esr ceramic cap, the value is around 10uF-22uF which will be helpful
2. choosing low esr bulk capacitor or…
Part Number: LMR16030PEVM The following circuit is prototyped. Vin = 48V Vout = 24V
From the measurement results, the output voltage decreased according to the load. 100mA = Vout: 24.1V 500mA = Vout : 22.9V
1ch = Vin 2ch = Vout 3ch = Iout
If Vin…
Hi Sowjanya,
Thanks for the additional information. If the IC is burnt, thermals are the primary suspect.
For designs like this, it is recommended to have ground layers in between the top and bottom plane with thermal vias under the thermal pad in order…
here is the EVM request page, please login and better with your company email.

Hi Andy, Thank you for your reply.
Then, as shown in the figure below, I will consider mutual replacement with a capacitor with a practical amount of 16nF as CSS.
For LMR16030P, set CSS to DNP and open PGOOD.
Or we can place 16nF.
The circuit of…
