Other Parts Discussed in Thread: LM5155
My customer is trying to evaluate using LM5515EVM.
However, 6V is the minimum value for Vin of LM5155EVM-BST.
The input operating range of the LM5155 is 3.5-V to 45-V Operating Range, so I think it can be used even with Vin = 3.7V.
Is it possible to operate with Vin = 3.7V, Vload = 24V, Iload = 1.5A by remodeling EVM?
I did a simulation with Webench.
I was able to obtain a circuit diagram similar to EVM.
Therefore, we believe that it is feasible by changing the EVM component constant.
