Altera Corporation is making available a new power conversion solution that makes it easier for board developers to design point-of-load power solutions and achieve higher FPGA performance at lower system power. The new power conversion solution, a monolithic 40A driver plus synchronous MOSFET powertrain, has been optimised to meet the core requirements of Altera”s high-performance Stratix V, Arria 10, and Stratix 10 FPGAs and SoCs.
It offers systems designers the high-density, high-efficiency power conversion they require when integrating high-performance FPGAs into their system.
The new powertrain, (part number ET4040), meets the stringent core voltage requirements of high-performance FPGAs, processors and memory. Systems designers can leverage the 40A powertrain to efficiently power the FPGA”s core supply rails in single-phase or multiphase configurations. It can also be used in VDDQ supply rails for DDR3, DDR4, and QDR memories as well as supplying all high-current supply rails for ASIC and ASSPs that are used in high-end servers and communications infrastructure systems.
“Over the past year, Altera has delivered a variety of solutions optimised to power Altera”s FPGAs and SoCs with the performance, power density and efficiency system developers require,” said Mark Davidson, marketing director of Altera”s Power Business unit. “This powertrain complements Altera”s Power SoC DC-DC converters to offer systems engineers new ways of designing products with the smallest, most efficient power solutions, optimized to meet the most demanding requirements and deliver needed performance.”
The ET4040 powertrain offers 40A continuous output current over industrial temperature range (-40C – + 85C) and across an input range of 4.5V to 14 V. It delivers low Rds-on and low switching loss while enabling high efficiency at high frequencies (up to 3 MHz switching frequency). The device”s on-board monolithic current sense enables use of a lower loss inductor for better system efficiency while also providing a vast improvement in reliability and thermal performance over competing solutions on the market.
