DataSheeT Intel Enpirion Power Solutions 0 EM2040N01QI 40A PowerSoC Step-Down DC-DC Switching Converter with Integrated Inductor Description Features The EM2040 is a fully integrated 40A PowerSoC Integrated inductor, FETs, and controller synchronous buck converter with digital non-linear Wide 4.5V to 16V V range IN control loop. It features an advanced controller, 0.5V to 1.325V V range OUT gate drivers, synchronous MOSFET switches, and a 11mm x 17mm x 6.76mm QFN package high performance inductor. Only input and output o 90% efficiency at V = 12V V = 1.2V IN , OUT 2 filter capacitors and a few small signal components Optimized total solution size of only 365 mm are required for a complete solution. The digital Meets all high performance FPGA requirements loop enables a reduction in output bulk filter o 0.5% set-point over line, load, and capacitors. temperature o Output ripple as low as 10 mV peak-peak Differential remote sensing and 0.5% set-point o Differential remote sensing accuracy provides precise regulation over line, load RVSET resistor for programmable V OUT and temperature variation. Very low ripple further RTUNE resistor for single resistor compensation reduces accuracy uncertainty to provide best in Tracking pin for complex sequencing class static regulation for todays FPGAs, ASICs, RoHS compliant, MSL level 3, 260 C reflow processors, and DDR memory devices. Applications The EM2040 features high conversion efficiency and superior thermal performance to minimize High performance FPGA supply rails thermal de-rating limitations, which is key to ASIC and processor supply rails product reliability and longevity.
