Part Number: LM3488
Hi,
i'm trying to obtain an output voltage at the output of LM3488 of 100V by changing the feedback resistor to 368.315kOhm: from the picture i'm obtaining an output of 80V, something wrong with my schematic? could be due to the limited VDS(max) of the MOSFET or are there any other limitation? the mosfet i'm using is CSD19538Q3A.
Moreover, i would like to decrease my input voltage from 5V to 3V; in this case i know my MOS would'nt be suitable because of its 3.6V Vgs(th) , do you have any other PN to suggest? I've seen in the datasheet that you suggested IRF7807, do you think it could be used for an application of 3V to 80V?
Thanks,
Elisa
