The power requirements of high-end FPGAs are becoming more and more complex, with increasing numbers of power rails, tighter tolerances, complex power-up sequencing requirements, and so forth. In order to address this problem, Altera acquired Enpirion in the summer of 2013. Enpirion's broad portfolio includes 100% coverage of FPGA point-of-load power needs. (See Altera & Enpirion – great things to come.)
We are now starting to see the fruits of this acquisition. Altera has just announced a new powertrain component (part number ET4040) that meets the stringent core voltage requirements of high-performance FPGAs, processors and memory. This monolithic 40A driver plus synchronous MOSFET powertrain is optimized to meet the core requirements of Altera’s high-performance Stratix V, Arria 10, and Stratix 10 FPGAs and SoCs.
ET4040QI typical application circuit.
The ET4040 powertrain offers 40A continuous output current over industrial temperature range (-40C to +85C) and across an input range of 4.5V to 14 V. Click here for more information.
