LM26420: 3.3V Output with Input between 3.0V and 4.2V

Brenton Yiu

Part Number: LM26420

I'm looking to use the LM26420 in a design. The input voltage will be from 3.0V to 4.2V and I would like the output voltage to be 3.3V. Will this part work for my design requirements?

Hi Brenton,

The 3.3V Vout is possible from a 3V to 4.2V supply. But depending on the losses on the board and the passives used there could be slight variations on the efficiency. I recommend to test this use case before actual implementation.

Is a dual buck converter necessary for your application? If not, we could look into alternative newer solutions.
