Part Number: TPS63030

Hi,

Typical application schematic seemed to be changed on the datasheet as below.

Has any problem ever occurred with VIN-VINA direct connection?

If yes, could you let me know the abstract of problem?

Best Regards,

Hi Kuramochi,

this was done during a datasheet cleanup. Both connections work and are functional.

With the the open connection between you can have a filter on VINA pin (internal 100 ohm with external C3=~100nF) to make the internal voltage more stable. This will reduce the output ripple.

Julian
