LTC7871 buck-boost converter design problem and high voltage high power DC-DC boost converter design help

Hi Zhafran,

5KW is not an easy task and requires significant power design experience and most probably time. If you just want to study a boost converter or demonstrate its function, you don't need to build a high power, expensive and bulky design not to mention risky (96V is high voltage.)

This product is new so I don't see available demo board yet. You may want to check LT8551. Though not capable of 96V, it has an available demo board that is a good reference design.

In many cases, the datasheet contains enough information to design the converter with someone having good power engineering background.

Thank you very much sir for your feedback and I will take consideration for that. However, my supervisor still insists on producing 5kW power output which basically will supply power for the electric car. That's why he needs a huge power output in order to make the EV car lasts longer on the road. Because of that I will try to test out LTC7871 if my supervisor demands.
