The power conversion product is a monolithic 40A driver-plus-synchronous MOSFET powertrain, optimised to meet the core requirements of Altera's Stratix V, Arria 10, and Stratix 10 FPGAs and SoCs.
ET4040 meets the core voltage requirements of high-performance FPGAs, processors and memory. Systems designers can use the 40A powertrain to efficiently power the FPGA's core supply rails in single-phase or multiphase configurations. It can also be used in V DDQ supply rails for DDR3, DDR4, and QDR memories as well as supplying all high-current supply rails for ASIC and ASSPs.
The ET4040 powertrain offers 40A continuous output current over industrial temperature range (-40C to +85C) and across an input range of 4.5 to 14V. It delivers low R ds-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.
