DC-DC converter for embedded computer-on-modules
15 November 2011
Enpirion’s EN5339 3-Amp PowerSoC integrates the controller, power MOSFETs, compensation network and inductor.
They are integrated into a solution that reduces the traditional engineering analysis and design effort associated with discrete DC-DC converter designs.
Its small solution footprint and slim profile offers customers – who develop diverse form factors such as Ultra COM Express, PC104, Qseven, ATCA Advanced Mezzanine Cards (AMC), Compact PCI and others – an important new alternative.
The EN5339 fits into a 55 mm2 solution area with a 1.1 mm profile. High-density embedded computer-on-modules, in particular, require this small area and often a low profile to enable bottom-side PCB mounting. Keeping up with the demands of embedded, industrial and storage applications, the EN5339 enables a 20 percent solution footprint reduction and 40 percent lower profile compared to previous Enpirion 3 Amp products. The small size and low profile enables highest-density computer-on-modules, densely stacked multi-board design and mounting on the backside of PCBs.
Fully validated and proven PCB layout and design files are provided; enabling customers nearly 100 percent first-pass reported success. In addition to EN5339’s competitive cost, Enpirion PowerSoCs require fewer external components (typically 3 to 6). EN5339’s low ripple (6 mV) and EMI eliminate the need for external noise filters, while its thermal performance and construction negate the need for heatsinks.
PowerSoCs achieve 21,800 years mean time between failures (MTBF). Enpirion high-efficiency devices are truly industrial graded and do not require load de-rating at 85° C ambient temperature. PowerSoCs are specified, simulated, characterised, validated and manufacturing-tested as a complete power system –which, when coupled with tightly controlled IC manufacturing processes and fewer total components, yields unsurpassed reliability.
