Enpirion’s DC-DC converter for power management in SSDs

HAMPTON, USA: Enpirion, the leading innovator of the industry’s smallest point-of-load DC-DC converters, announced a new member of its power IC portfolio targeted at solid-state drives (SSDs) as well as industrial embedded applications.

The Enpirion EN5339 3 Amp power system-on-a-chip (PowerSoC) integrates the controller, power MOSFETs, compensation network and inductor into one highly compact solution that significantly reduces the traditional engineering analysis and design effort associated with discrete DC-DC converter designs. Its slim profile offers Enpirion’s wide base of customers – who offer diverse form factors including SATA, PCIe, mSATA and others – an important new alternative. The EN5339 has already landed more than 20 design wins ahead of its official market release.

“Enpirion’s portfolio of PowerSoCs supports our hardware designers in easing the process of bringing to market numerous platforms, form factors and capacities,” said Jonathan Hinkle, memory system architect, Viking Technology, a leader in SSD, DRAM and hybrid technologies for the enterprise storage market. “The EN5339 is a nice addition to Enpirion’s lineup and helps streamline our power design efforts by eliminating cumbersome steps and needless iterations.”

The EN5339 fits into a 55 mm2 solution area with a 1.1 mm profile – setting the bar for the smallest 3 Amp solution available. Small form-factor SSDs, in particular, require this small area and height. Keeping up with the demands of storage, embedded and industrial applications, the EN5339 enables a 20 percent solution footprint reduction and 40 percent lower profile compared to previous Enpirion 3 Amp products.
