Avnet Abacus announced the availability of EN5339 from Enpirion, which is claimed to be the smallest 3A point-of-load DC-DC converter around. Targeting embedded computing applications as well as solid-state drives, the 3A EN5339 system-on-a-chip integrates the controller, power MOSFETs, compensation network and inductor into one highly compact solution that significantly reduces the engineering and design effort traditionally associated with discrete DC-DC converter designs.
Keeping up with the demands of embedded, industrial and storage applications, the EN5339 enables a 20% footprint reduction and a 40% lower profile compared to previous Enpirion 3-Amp products. With a footprint of just 55mm² and a profile of just 1.1mm, the EN5339 is particularly suitable for high-density embedded computer-on-modules which typically require such a small area and low profile to enable under-side PCB mounting. The POL converter is suitable for equipment based on a diverse range of form factors such as Ultra COM Express, PC104, Qseven, ATCA Advanced Mezzanine Cards (AMC), Compact PCI and others.
