Tool/software:
Hello,
I need a new Booster Design to Boost 5V to 12V. I simulated the LM27313 in WEBENCH Power Designer.
All seems ok but if I looked to the Iswitch Waveform I was surprised that there are current spikes up to 6A-7A. The spike has a short time under 1µs and is highest in state of no load (idle).
The spikes may come from the capacitance of the integrated FET on the Drain connection!?
My question: Is the functionality given or switch the current limiter to an error? Does the high current damage/destroy the integrated components?
In other words, Does the LM27313 have leading-edge blanking integrated?
Thanks for your help.
Best regards
Jochen
