Tiny Power Source For FPGAs


Altera announced a new 6A PowerSoC DC-DC step-down converter ideal for powering the Altera Cyclone and MAX families of FPGAs and optimise power usage in a variety of systems requiring a tiny, accurate, high-efficiency power source.

The highly integrated and fully tested PowerSoC (EN6362QI) with integrated inductor adds to Altera’s Enpirion power products and claimed to be the first in a new generation of low-VIN (input voltage) power products with industry-leading power density. The device also improves performance in the areas of conversion efficiency, output voltage accuracy, load transient response, and output voltage ripple which help to target stringent system power requirements, reduce costs and accelerate time-to-market.

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

Key features of the EN6362QI PowerSoC include increased power density of 56 W/cm2, optimized total solution size of 170 mm2, 1.5 percent output voltage accuracy over line, load, and temperature, excellent load transient and output voltage ripple, low EMI, full suite of protections, and programmable soft-start. Over discrete power supply solutions, the chip results in very low FIT (failure in time) rates and dramatically improves system reliability.

“The innovation behind this product reinforces the Enpirion solutions’ leadership in integrated power solutions as we are continuing to drive density higher and solution size smaller, while raising the bar on performance specs such as accuracy and EMI, which are needed by FPGAs and other advanced electronic systems. With its ease of use, the EN6362QI allows our customers to save design time and cost without sacrificing performance by eliminating costly board spins, and focusing resources on system design, not power”, said Mark Davidson, senior director for Power Products, Programmable Solutions Group, Intel.
