tubbytwo Posted June 27, 2006 Report Share Posted June 27, 2006 I know the max for the ML317 is 37VDC, but is there a way to boost that to 90VDC at about 30mA? I'm looking for an alternative to four 22V Zeners. The arguement was that IF a Zener shorted, the rest could also go. Quote Link to comment Share on other sites More sharing options...
indulis Posted June 28, 2006 Report Share Posted June 28, 2006 If you look at the LM317HV spec, you will see that the max input to output voltage is 60V. That does not mean 60V is it!!! You could have 120VDC in and 100V out which is fine because you haven't violated the 60V max differential. Quote Link to comment Share on other sites More sharing options...
on1aag Posted October 18, 2006 Report Share Posted October 18, 2006 There is a high voltage version of the LM317, it's the TL783. ;Don1aag. Quote Link to comment Share on other sites More sharing options...
