Hello Anirudha,

Yes, you are parallel operation like similar manner for this TPS22996H-Q1 as well.

Thanks

Hello Amrit,

As per TPS22968x-Q1's parallel configuration, one CT capacitor is sufficient for both CT1 and CT2 for slew rate control.

Similarly, please explain how to do the parallel configuration for the TPS22996H-Q1 IC with respect to RT1 and RT2.

Can I use a single resistor RT or do I require to use two resistors for RT1 and RT2?

Please, explain with the application diagram attached below:

Thank You

Hello Anirudha,

You can connect a single RT. while calculating RT, make sure to take the summation of current for both ON pins.

Thanks

Hello Amrit,

I would appreciate if you can provide an example circuit design and calculations for desired slew rate of 1000us. The "ON" pins should be naturally pulled high i.e., the outputs should be normally on.

Thank You

Hello Anirudha,

Please find below section from datasheet to calculate rise time.

Last equation, you can find the RT value.

Thanks

Amrit
