TPS92200: Efficiency Curve

Tsugumi Murata

Part Number: TPS92200

Hello,

I have two questions I would like to get a clarification on for the efficiency curve shown on the datasheet (p.9 Figure 6-15 , Figure 6-16).

1. Is this for analog dimming or PWM dimming ?

2. Is this the efficiency for VOUT or LED?

Thank you for your help in advance.

Sincerely,

Tsugumi

Hi,

I am using the TPS92200D2, but I can't tell from the datasheet which one the efficiency graph is referring to.

Hi Tsugumi,

1.I have to check and reply you later.

2.It's for VOUT, which means it includes sense resistor power dissipation.

Robin
