Part Number: TPS65987D

Hi Team,

I plan to use TPS65987D in the following configuration :

PP1 switch: Sink only, PDO1

PP2 switch: Souce only (5V, 0.9A)

PP3 switch: Sink only , PDO2, PDO3, PDO4,

Sink PDO-s:

PDO1: 5V, (12W)

PDO2: 9V, (12W)

PDO3: 15V, (12W)

PDO4: 20V, (12W)

My question : is it possible, and if yes, how to achieve this with the application customization tool ?

Thanks,

Zoltan

Hi Zoltan,

Unfortunately this is not possible with the current application configuration tool. May I ask why you are wanting to separate the sink PDO's from one another?

Hi Adam,

Thank You for quick reply.

Separating the pdo's allows for a simpler and less expensive power supply solution on device side.

Regards,

Zoltan

Hi Zoltan,

Would you be able to elaborate on this? I would imagine that having 1 DCDC would be more cost effective than having two. Do you have a system block diagram that you would be willing to share? You can send me a private message on the forums as well if you are more comfortable sharing it there. Click on my profile, and send me a request.
