Hi,

If using the internal LDO, should EXTVCC be connected to high voltage or left floating? Thanks.

Hi Che Wen,

The EXTVCC pin can be connected with VCC pin or left floating to select internal LDO. Both are ok.

BRs,

Hi, i assume the same is true for TPS55287 and similar ICs from that series, right?
