5V Buck converter, TPS54821
« on: April 23, 2020, 09:09:14 am »
Hi,
I want to drive a spartan 6 device with TPS54821, I need to be able to get 3.3V @ 6A with 5V input, also the upper input limit is 12V, I came across this TPS54821 using TI webench, I want to make sure it can generate 3.3V @ 6A with 5V input, has anyone used this puppy before? Vin - Vout headroom enough?

Hello , i dont know about the Ic you have mentioned but i have used LM61460  its a wide input voltage automotive buck regulator . Im happy with the performance . I have attached efficiency measurements and schematic  . I think it will be fine for your application .  :-/O :-/O

Aparently made for 100% Duty Cycle operation so it should be fine.
