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 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…
