Tool/software:
Dear Experts,
we have a design for 12VDC input, 38VDC output, boost power supply by LMR64010.
it's working, the output is about 38V as expected.
but unfortunatly, when look at the waveform of SW, there is a big concern now.
the Vmax is 47V and the Vmin is -14V on SW pin when Vout=38VDC.
it's said in datasheet, the max range of SW is -0.4 to 40vdc
out of spec obviously.
since snubber was implemented, did we missing anything? or does it mean it's not safe for a 38VDC boost design by LMR64010?
Thank you very much.
Alex
