TPS25921A: adding two in parallel to achieve higher current.

Ricardo Dias

Part Number: TPS25921A

Hello,

Can I add two TPS25821A in parallel to achieve more current? If yes, can both chips share the same passives?

I am not sure about current limit resistor connected to ILIM pin as there will be a current source from each part going down this common resistor.

Thanks

Hi Ricardo Dias,

Yes, you can parallel TPS25921A devices. Please refer app note at www.ti.com/.../slva836.pdf for details on how EN, SS, ILIM pins are configured in parallel operation.

Can you share your system requirements and end application use case, so that I can suggest suitable part.

Best Regards,
Rakesh
