thanks again for your help.As the LT8570 is pin compatible to LT8580, I can replace it on my pcb.So for now, my question ist answered.
I briefly considered a doubler, and especially given the circuit charges an element and draws virtually no current. In the end, I moved to the LT8570 which, fortunately, has a very nice and apparently tested design for -48V.
Thanks for the suggestions…
I am using the circuit given in page number 24 in datasheet "https://www.analog.com/media/en/technical-documentation/data-sheets/85701fa.pdf"
to generate -15V with 24V as input.
I am able to measure only -2V after assembly. Also getting…
As the title says, can I use the resistors similar to the one above, by replacing the FBX resistors, and the L, C and diodes that adapt to the output voltage to produce +-53V, two voltages. My input is +15V.Thank you
