Altera has announced a 6A PowerSoC DC-DC step-down converter as addition ot its Enpirion power products portfolio. The device is a full-featured, highly integrated and fully tested PowerSoC with integrated inductor. The company, which is now a part of Intel, said the PowerSoC (EN6362QI) is the first in a new generation of low-VIN (input voltage) power products that provide remarkable power density while improving performance in the areas of conversion efficiency, output voltage accuracy, load transient response and output voltage ripple.

These features help system designers meet stringent system power requirements and significantly reduce costs while accelerating time-to-market. The PowerSoC is geared for powering the Altera Cyclone and MAX families of FPGAs and can optimise power usage in a variety of systems requiring a tiny, accurate, high-efficiency power source.

EN6362QI PowerSoC

The EN6362QI PowerSoC is 45 per cent smaller than other power modules and 75 per cent smaller than most competing discrete (non-integrated) device implementations, noted Altera. It offers the highest efficiency of any comparable module, along with superior thermal performance, delivering continuous 6A at 85°C ambient temperature with no de-rating.

The EN6362QI PowerSoC is designed and manufacturing-tested as a complete power system, which results in very low FIT (failure in time) rates and dramatically improves system reliability when compared to discrete power supply solutions. Other key features of the EN6362QI PowerSoC include: increased power density at 56W/cm2; optimised total solution size of 170mm2; 1.5 per cent output voltage accuracy over line, load and temperature; excellent load transient and output voltage ripple; precision enable for sequencing; full suite of protections; low EMI; and programmable soft-start.
