Altera Corporation (Intel) offers a new power conversion solution that makes it easy for board developers to design point-of-load power solutions, while achieving the highest FPGA performance at the lowest system power, according to the company. The power conversion solution is a monolithic 40A driver plus synchronous MOSFET powertrain that is optimized to work with Altera’s high-performance Stratix V, Arria 10, and Stratix 10 FPGAs and SoCs.

AlteralogoDelivering high-density, high-efficiency power conversion, the ET4040 powertrain meets the 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,” said Altera. The device can also be used in VDDQ supply rails for DDR3, DDR4, and QDR memories as well as supply all of the high-current supply rails for ASIC and ASSPs that are used in high-end servers and communications infrastructure systems.

The ET4040 powertrain offers 40A continuous output current over the industrial temperature range of -40°C – + 85°C and across an input range of 4.5V to 14V. It delivers low Rds-on and low switching loss while enabling high efficiency at high switching frequencies up to 3 MHz. The device also features an on-board monolithic current sense that enables the use of a lower loss inductor for better system efficiency.

“Over the past year, Altera has delivered a variety of solutions optimized 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, in a statement. “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.”

Availability: The Altera ET4040 monolithic 40A driver plus synchronous MOSFET is available now.
