TPS562211: Factors of difference between datasheet and Webench

Hideki Hayashi1

Part Number: TPS562211

Tool/software:

Hi team,

Customer has run the Webench with TPS562211 and find "lower efficiency" than datasheet, and "strange curve".

Customer uses TPS562211 with 12V to 3.3V/500mA. What causes them? is it a transition point of Eco-mode and PWM mode?

Best regards,

Hayashi

Hi Hayashi-san,

Here's a quick reference to data captured using our EVM:

We'll look into this. This will take sometime.

Hi Hayashi,

You have to refer log scale version of the efficiency curve.
