TPS62811-Q1: Efficiency curve

Kazuki Kuramochi

Part Number: TPS62811-Q1

Hello expert,

I have question for TPS62811-Q1's efficiency curve.
Datasheet's efficiency curve seems that it is for TPS62814 due to output current condition is 4A.
Also, as far as I confirmed datasheet, All of specification except current limit threshold are same between TPS62811 and TPS62814.

Then, this is just confirmation but could I regard that TPS62814's efficiency curve until 1A is same as TPS62811's curve?

Thank you and best regards,

Hello Kazuki,

The efficiency curves are the similar, but for more detailed simulation you can refer to our models in the product page. Thank you!

Best regards,
Nikola

Hello Nikola,

Thank you for your swift reply.

I understand that we can probably regarding TPS62814's efficiency curve as TPS62811's efficiency curve.
But you recommend to use webench simulation due to efficiency depend on not only device performance but also external components.

If there is miss understanding, please let me know.

Thank you and best regards,

Hello Kazuki,

The efficiency curves in the data sheet are based on the BOM given in the table 9-2. In the webench simulation you can specify external components that you aim to use. Thanks!

Best regards,

Nikola
