LM5176-Q1: BIAS pin when unused - ambiguous

Part Number: LM5176-Q1

Hi all,

Question. Considering a boost-only application where BIAS input is not required. Can its pin simply be left floating?

Considering it's just an optional secondary power input, I assume this should be fine?

Webench spits out a design where BIAS is bypassed with a 100nF capacitor, even though it's not fed.

PSpice refuses to simulate with BIAS floating or simply bypassed like Webench showed me.

The datasheet makes no mention of what to do with the pin when unused.

Could anyone please clarify?

Thanks,

Joey
