What is power hold-up & energy storage management?

In this article, we discuss power hold-up and some energy storage management devices in the context of SSDs. Most, if not all, SSDs (solid-state drives) employ some sort of power hold-up scheme using an energy storage system. The power hold-up is used to protect the NAND memory during an unexpected power loss.

What is a backup energy IC?

This backup energy IC is characterized, according to its datasheet, as a “lossless energy storage and management unit targeted at the solid-state and hard-disk drive applications.”

Do SSD energy storage backup systems use capacitors?

Most, if not all, SSD energy storage backup systems utilize capacitors as the actual energy storage “tanks.” Based on various SSDs that I’ve seen online, the choice capacitors used for energy storage are tantalum caps, polymer tantalum caps, or good old-fashioned ceramic caps.

What is a DC/AC board?

The first board, called DC/DC board, consists of two input boost converters for the individual string inputs and a DC/DC converter associated with the battery stage. The second board, called DC/AC board, consists of DC-link capacitors, DC/AC converter and filtering circuits.

Who owns USB Type-C®?

USB Type-C® is a registered trademark of USB Implementers Forum. All trademarks are the property of their respective owners. VEDATROYEE GHOSH is a Systems Engineer at Texas Instruments Germany, where she focuses on solar energy within the Energy Infrastructure team.

Does Ti offer an enterprise SSD backup power reference design?

If you’re looking for, perhaps, a simpler approach by use of a reference design, TI offers their PMP30046, which is advertised as being an “Enterprise SSD Backup Power Reference Design.” The schematics to this reference design can be found here.
