LT3420 as HV power supply.

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.

Thank you,
