Other Parts Discussed in Thread: LM61495, , LM61480, LM3489, LM25148
Hi Team,
My customer is designing a 12~24Vin, 12Vout power, when 12Vin = 12Vout, they hope that the controller can close 100% duty(H side SW fully turn on) as possible.
Here is some of my questions :
- Does LM62460, LM61480, and LM61495 have the quick design calculation tool now?
- For 12Vin = 12Vout/5.5A design, do you think LM62460 can handle it without concern ?
- For the duty cycle parameter, how to define frequency foldback condition for DMAX 98% ? Does it need to set auto mode for frequency foldback?
- How to define the condition for DMAX(typ) 87%?
- Customer prefer FPWM mode, may I your suggestion about this application? Lout value, Fsw setting…etc
I think fixed_2.2MHz, Lout=1.5uH should be good.
BR,
Kai
