I am missing PI App notes on recent products compared to old ones like TOP-II, GX etc had. PH series have no app note available. e.g. more details required on following parameters :
> Resistor and Current characteristics for Rv
(also why der286 shows 4M from +ve bus only against typical schema showing along with 1M4 to Gnd ?)
> Resistor and Current characteristics for Rref (24.9k etc)
e.g. what is its behavior if its value changes a bit, say 5%
> BP pin said to have Capacitor dependent gain but no charts and details
> FB pin chart doesnt shows only normalized chart instead of uA vs Dmax values
why PH series is in Archived Products, is it going to be obsolete ?
is there replacement for PH device that have Universal input/CC/PFC/isolated/PSR all capabilities ?
