Dual output +50V and -50V DC/DC boost

Hi all,

i'm looking for DC/DC boost with dual output - one for +50V and the other for -50V.

The input voltage is between: 10V to 30V

and the load current from each output is ~5mA (so 10mA from each output should be suffice) .

I don't want to use transformer in the design.

Thanks a lot

PMP10687A(001)_LM5022_80V_Sch.pdfItay hello and thank you for your interest in Texas Instruments' TI Designs. I have conferred with our Power Supply Design team on your question. While we don't have a hardware solution built, we do have a paper design developed that conceptually covers what you were asking about. Please take a look and advise if this works for what you are looking for.

Best Regards,

Thanks you John, that works for me....

Can you share the BOM for the other components?
