Hi Sir,
May I have your help to review the SCH and layout as below:
Now we facing missing pulse issue, please refer below waveform, Ch1: UCC24612…
Hi Ben,
The power MOSFET is quite capacitive (Qg = 49nC at Vgs = 10V and Qgd = 13nC), resulting in high switching and gate drive losses that may become particularly evident at light loads.
Given the rated output current of 3.5A, you can use a higher…

Part Number: PMP20021 Other Parts Discussed in Thread: CSD18504Q5A , LM25119EVAL , LM25119 Hello,
I have a 24V to 12V / 20A buck converter application without ambient air-flow with ambient temperature of 50deg.C.
I was reviewing PMP20021 reference design…
FET is CSD18504Q5A, so Rdson is 7.5m ohm.
The combination, Rdson is 15.6m ohm and RLIN is 150 ohm , is OK and ILIM hit about 3A.
But the combination, Rdson is 7.5m ohm and RLIN is 75 ohm is NG and ILIM did'nt hit and RLIM resistor burned.
Do you know…

I had a design went through below for a 24V to 5V@15A buck a few days back.
Design : 4561043/188 LM5116MHX/NOPB
LM5116MHX/NOPB 22.0V-26.0V to 5.00V @ 15.0A
Now I ran the same…
