Part Number: PMP20850 Hi team,
This TI design Vin spec which could achieve -72V ~ -36V, but the test result show 36V, 48V and 72V.
May I know how to setup the test environment to clarify our -48V capability?
Thanks!
You can search the TI reference design library here . I gave a -48V design example as PMP20850. PMP20850 at least gives an example of the power stage configuration but it it using the3 UCC2897A PWM. You want to use the LM5026 which hopefully you can configure…
Part Number: PMP20850 Other Parts Discussed in Thread: PMP21103 Hi,
My customer also want to modify the design to 12Vout, and Iout=3A. Please suggest, thanks.
Part Number: PMP20850 HI Team,
My customer would design an application transforming from -48V to 12V, with isolation protection and it seems PMP20850 also fits the spec. How to modify the design such that it can output 12V? Thanks.
Best regards,
Andy…
Hello Feng bin Su,
This reference design could be a starting point: https://www.ti.com/tool/PMP20850
In general I think an isolated hard switchng flyback could be another possibility, driven by LM5156 for example.
