I need a HV (250-300V) power supply to bias an avalanche photo-diode (current ~1 mA max). The spec sheet of the LT3420 says it can be used as a supply but there are no details. Is it possible to have it always charging? And not have the charging block turn on and off. Or should I try another IC? (LT3750?) Or something like figure 13 from here.
