Board developers can design PoL and achieve the highest FPGA performance at the lowest system power, says Altera, using the monolithic 40A driver and synchronous MOSFET powertrain, optimised to meet the core requirements of its high-performance Stratix V, Arria 10, and Stratix 10 FPGAs and SoCs. The powertrain, (ET4040) meets the core voltage requirements of high-performance FPGAs, processors and memory for systems, says the company. Designers can leverage the 40A powertrain to power the FPGA's core supply rails in single-phase or multi-phase 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. The powertrain operates at -40 to 85°C and across an input of 4.5 to 14V. It delivers low Rds-on and low switching loss while enabling frequencies up to 3MHz switching frequency. There is an on-board monolithic current sense allowing a lower loss inductor to be used.
