TPS65580: Power sequencing

Ernest Yong

Part Number: TPS65580

Hi Team,

I have a question regarding the TPS65580 on whether it has internal power sequencing for the Enable pins? If it does not, could you suggest how we can apply power sequencing for this IC as my customer plan to output 3.3V, 1.8V and 1.2V.

Many thanks!

Hi Ernest,

Thanks for reaching out! Could you please kindly let me know customer and application? Is it for FPGA? TPS65261 can support automatic sequence/ external power sequence.

Kindly let us know for anything unclear. Thanks!

Hi Lucia,

Thanks!

I do not wish to reveal customer name on a public forum, but I can send you a on private message instead. This application is not used for FPGA. It's to step down 5V to supply power to multiple devices such as USB hub, PCIe switch, etc.

Best Regards,

Ernest
