TPS549D22: VDD pin maximum current consumption

Muhsiu Wei36

Part Number: TPS549D22

Hi Team,

What's the maximum current consumption of VDD pin of TPS549D22 when converter is switching? We need to this data to select correct input filter resistor power rating. thanks.

Hi Muhsiu,

The max spec for the bias current is not specified in the datasheet. If you are using a 1 ohm resistor, 0603, that should be good enough.

With a 65mW power rating, that is closed to around 250mA of current that can be handled.

Regards,

Gerold
