Dear TI Team,

I have a Question.

If you do not use the Boost function of the LM48511, can you confirm that V1 and PV1 should be connected to SW?

Below is a circuit configuration without Boost function.

Please review.

Thanks.

Hi Chun,

Actually data sheet mentions some details on supply connections when boost is disabled, in section 7.3.5: www.ti.com/.../lm48511.pdf
External supply voltage between 5V and 8V should be connected directly to PV1.
