TPS65218: Zynq 7000 Power Sequence

Part Number: TPS65218
Other Parts Discussed in Thread: PMP8251, , , TIDA-00478

Hello, I am doing a design with a Zynq 7015 and am looking for solutions on how to sequence the power rails. I see the TPS659110 and the TPS65218 can power the Zynq but don't these PMICs need to be programmed with the sequence first or do they come with the sequence programmed in? I have searched the site and have found:

Can anyone help me find a solution please?

Thank you

Joe

Joe,

You want to use the TPS6521815. This version is intended for customer programming, and is referred to as a "blank EEPROM" device. In other words, you apply power to the part (5V typical) but all of the outputs are disconnected from the sequencer until you re-program the EEPROM memory and cycle power to the device.

The BOOSTXL-TPS65218 board is intended to be used to program TPS6521815 samples for prototyping your design.

The TIDA-00478 documentation needs to be updated to use the updated part number, and I apologize for any confusion this may have caused.

Hello, there a way where it can be programmed at the manufacture and you order say 100 pieces?

Thank you

Joe,

Unfortunately, we do not offer programming at the factory for quantities on the order of 100 pcs.

If you visit https://www.ti.com/diypmic you can read more about how to program the PMICs yourself.

Or, you can following the instructions on this page that say:
