Part Number: TPS54331EVM-232 Hi! I have some question about TPS54331EVM.
Q1: When I test TPS54331EVM-232, output ripple doesn't look like User Guide providing waveform. What's wrong with it?
my test(Green: DC output voltage; Yellow: output ripple;…
Part Number: TPS54331EVM-232 Hello Guys,
Good day.
Our customer are using this off the shelf board in our enclosure which is in design phase so they need the step file of 3D PCB (Board’s 3D models) to fit them in enclosure. Is this available?

Part Number: TPS54331EVM-232 Hi Teams,
We design a buck circuit by TPS54331DR which has been used for many years. recently a board which failure in field and local temperature is -30 C. As checed found the buck output voltage cannot keep stable at low…
Part Number: TPS54331 Unless I am completly missing something and this is quite possible, there are a couple of things slightly confusing me at this point!
The first one is in datasheet: http://www.ti.com/lit/ds/symlink/tps54331.pdf Equation (13)…
hi Sina,
please note that the waveform of the switch node (the 1st one you posted) tells us the TPS54331 is working in DCM mode, that fits with the no load / light load test conditions...
while when VIN reduces to <6V the current ripple decreases…
