I'd like to use the LT1619 as a flyback converter from 10V to 1200V with Iout<1mA. If Vin is too high, also lower values of Vin are acceptable.
I'm looking for an application note or a reference design to implement it in the simplest possible way.
Efficiency is not an issue.
The reason that I chose the LT1619 for this task is that I want to use a PWM signal as the enable (in the S/S pin), so also other controllers with this capability are possible, but I didn't find any alternatives.
