Hi Team,

Could you please help to check below questions on TPS92200D2? Thanks a lot for your support.

#1 What is the minimum voltage for Vin-Vout? From datasheet, it shows it can reach to 99% Duty cycle. Could it work with Vin=15V and Vout=14V?

#2 For DIM pin, could it work under 1.8V,3.3V and 5V voltage for dimming purpose? From datasheet, it shows DIM maximum voltage is 7V.

#3 For DIM pin, if this pin been pulled to 0V for a long time like 5S/10S, would this device enter into Shutdown mode?

Thanks a lot for your support to check.

Best regards

Hi Jessica,

For your question,

1#, TPS92200 can support Vin=15V and Vout=14V.

2# TPS92200 can support MCU with 1.8V / 3.3V / 5V supply. The pin itself can support 7V max voltage.

3# Pulling down DIM pin longer than tDIM_OFF will shut down the device.

Thank you!

Best,

John.
