On 1V～6Vin ⇒ 5Vout/0.5A SEPIC solution, LM3488 can't use typcal design because of 2.97V_UVLO.

Customer thinking separate line, please see below.

Is it no problem?

When there are other recommended devices, please let me know.

Best regards,

Hi Satoshi,

Connecting the VIN to a separate power source should work.

The LM3488 should work, but I would suggest using the LM3481 for this. We already have a SEPIC EVM available for the LM3481, so they can test this out more easily by reworking the EVM.
