Hello
According to your experience is it possible internally for any reason or a failure to connect the input with the output? The component is used to create 12V from 48V. Is it possible internally to put the MOSFET in short or impendent circuit…
Yes, i agree with John that an overvoltage condition will damage the IC and cause the IC to blow up.
Even a ringing on the input voltage (VIN) above max spec will do it
Thanks

Part Number: LM5574-Q1 Hi
The packaging information of LM5574-Q1 is written LM5574Q0MTX/NOPB and LM5574QMTX/NOPB.
What is the deffierence between "0"ver and non"0"ver?
Best regards,
Yokota
Part Number: LM5574 I'm using the LM5574 as a positive voltage in, negative voltage out switcher. In reviewing the pc board layout tips, it mentions methods for connecting the LM5574 GND connections to topside copper traces and GND planes using vias.…
LM5574- Using WebBench, I made an inverting switcher using the LM 5574. The parameters I used were 7<Vin<9.5, Io (max) = .015A. The resultant circuit initially didn't function at all. I ran WebBench again using an alomost identical part (LM5575…
Other Parts Discussed in Thread: LM5574 , LM46000 Please let me know about two points below of LM5574 maximum rating.
①Is there spec information of SW to GND transients?
For example, LM46000 datasheet page-4 described "SW to PGND less than 10ns Transients…
Other Parts Discussed in Thread: LM5574LM5574 I really need help with a design. I built a +9V to -50V converter using the LM5574. With no load attached, its running at max duty cycle. I've replaced the output capacitor and still same. I used WebBench…
Hi all, I have a question. LM5574 has 76V maximum voltage input. I didn't find the limiting minus voltage input from datasheet. Other devices have limiting minus voltage input in absolute maximum ratings. Could you let me know about Vin to GND absolute…

Hi Team,
Could you help answer the questions below I have from my customer please?
"My query is regarding the maximum input voltage... The absolute maximum voltage is specified in your datasheet as 76V. The maximum input voltage we can expect to experience…
