TPS628513: SS/TR tracking behavior

Cameron Wutzke

Part Number: TPS628513

Tool/software:

Hello! The datasheet verbiage makes it sound like SS/TR voltage will equal the output voltage.

Could you please confirm?

We hope to PWM (with RC filter) into the SS/TR pin, with our PWM voltage at 1.8V. Our ideal Vout is 3.0V , ultimately driving an LED. Analog dimming would be neat

Or maybe we do something like this on the FB pin:

Hello,

Voltage Tracking is explained in section 10.3.1 in the d/s. Was that helpful?

Let me also share an App note on Tracking.

If that does not help, please share more details on the application scenario.

Regards,

Febin
