Framingham, Mass. - Artesyn Technologies' ultracompact SIL30E and SMT30E point-of-load (POL) converter modules deliver up to 30 amps at 0.8 to 3.63 volts for densely packed ASICs, network processor and DSP applications. That's 75 percent more current than provided by comparably sized products, according to the company. The two-phase, 2-MHz synchronous buck converters, for use in distributed power architectures with an 8-14 volt intermediate bus, are fully compatible with similar products from members of the Point-Of-Load Alliance (POLA), which includes Texas Instruments, Astec Power, and Ericsson Power Modules.
The SIL30E features a small footprint; the SMT30E features a low profile. The SIL30E vertical-mount modules have a footprint of less than 4 cm2 (50.8-by-7.8 mm), and the surface-mount SMT30E modules measure 33-by-13.5 mm by only 8.1 mm high, suiting them for systems with tight card pitches. Corresponding current density for the SMT30E is 8.3 A/cm3, and efficiency is 92 percent (12-V in, 3.3-V out model). The new 30-amp model, in place of two traditional 15-amp POLs, is designed to cut board real estate requirements in half and reduce the bill of materials by up to 40 percent. The converters' small size and low internal power dissipation enable designers to place them immediately adjacent to the load, even on very densely packed boards.
Both series, rated for operation over -40 to +85°C, are suited to forced air or convection cooled environments. The SIL30E can deliver its full 30-amp output at up to +60°C for 200 lfm airflow.
These converters feature remote-sense and remote on/off facilities, have no minimum load requirement, and are comprehensively protected against over-temperature and short-circuit conditions. The converters carry a full set of international safety approvals including EN60950 and UL/cUL60950.
The converters are priced at $23 each in 1k quantities.
Standard lead-time for both models is stock to 6-8 weeks.
