Tool/software:
Hello E2E Experts,
Good day.
LM76003RNPR 36V-36V to 3.30V @ 3.5A LM76003RNPR 36V-36V to 3.50V @ 3.5A
LM76003RNPR 36V-36V to 24.00V @ 3.5A
I created the circuit in KiCAD and had the three circuits built by JLCPCB, however the outputs are as follows:
to 3.30V: output varies continuously with extremes at 3.5V and 6.1V. It doesn't reach 3.3V and it is not stable
to 3.50V: output varies continuously with extremes at 3.8V and 5.9V. It doesn't reach 3.5V and it is not stable
to 24V: output is very stable at 24.95 - 24.97 Volts, but it's not 24V
Can you determine why the outputs are as I have listed from the limited information I have provided.
The inductors recommended by Webench are smaller than what is recommended in the datasheet. And from memory the input and output capacitors are different. Can you please help?
Regards,
TI-CSC
