Hello everybody,
I’m designing a circuit (the power part in the attached file) that requires both 3.3V and 15 V supply. I’m not so expert in powers electronic so I’m asking your help. I’m using 2 Traco Power DC/DC converters (2W models: TES 2N-4813 (from 48V to 15V) and TES 2N-1210(from 15V to 3.3V) (https://www.tracopower.com/products/browse-by-category/show/dc-dc-converters/smd-package/tes-2n/1/). Are correct the two DC/DC converters in cascade as I designed? Futhermore I’m thinking to exploit a LPF to isolate the line from the switching regulators and a line protections circuit as well. Please someone could help me to determine the L, C and diodes (zener, schottky and TSV) values or give some suggestions and help about. I will very appreciate any support.
Thanks in advance.
Kind regards,
Luca
