Data SheeT Intel Enpirion Power Solutions ED8401 Digital Multi-Phase Controller TM Multi Phase, Single Output, Fully Digital Step-down Controller with PMBus v1.2 Compliant Interface Description Features The ED8401 is a true digital multi-phase step-down Programmable digital control loops controller for non-isolated, high current DC/DC All Phases actively current balanced applications. A PMBus version 1.2 compliant Tracking pin for complex power sequencing interface provides setup, control, and telemetry. Vin Feed-forward Individual Tmon input for each Phase Differential remote sensing and 0.5% set-point Meets all high-performance FPGA requirements accuracy provides precise regulation over line, load o Digital loop for excellent transient response and temperature variation to provide excellent o 0.5% set-point over line, load, temperature static regulation for todays FPGAs, ASICs, o Differential remote sensing processors, and DDR memory devices. o Monotonic startup into pre-bias output The ED8401 can be configured and controlled in o Optimized FPGA configs stored in NVM any application by two methods, either in pin-strap Programmable through PMBus mode using onboard resistors, or using the PMBUS o V margining, startup and shutdown delays OUT interface. The customer can also configure the o Programmable warnings, faults and response device during engineering evaluation using the Operational without PMBus PMBUS interface, which offers a high degree of o RVSET resistor for setting V OUT flexibility and programmability, and then use the pin o RTUNE resistor for single resistor-based strap mode when devices are deployed in compensation production. The Intel Enpirion Digital Power Programmable Overcurrent Response Configurator provides a user-friendly and easy-to- o Latch Off (default) use interface for communicating with and o Hiccup configuring the device. Protection features o Over-Current Protection The ED8401 offers a scalable solution by operating o Over Voltage protection VIN VOUT in 4, 3, or 2 phase mode. Combined with the Intel o Under Voltage protection VIN VOUT Enpirion ET6160LI power stage, this enables an o Over Temperature optimized load current range to greater than 200A. o Restart and delay times Fuse-Based NVM for improved reliability RoHS compliant, MSL level 3, 260 C reflow Small 5mmx5mmx0.9mm QFN Package Applications High performance FPGA Core Supply ASIC and processor supply rails Page 1 15612 April 2, 2020 Rev BData Sheet Intel Enpirion Power Solutions: ED8401 Ordering Information Package Part Number Configuration* Package Description Markings 4-Phase ED8401P01QI 84011 5 mm x 5 mm x 0.9mm QFN40 500kHz 3-Phase ED8401P03QI 84013 5 mm x 5 mm x 0.9mm QFN40 500kHz 2-Phase ED8401P05QI 84015 5 mm x 5 mm x 0.9mm QFN40 500kHz EVB-ED8401P01 Evaluation board 4-Phase, 500kHz EVB-ED8401P03 Evaluation board 3-Phase, 500kHz EVB-ED8401P05 Evaluation board 2-Phase, 500kHz EVI-EM2COMIF GUI interface dongle * For alternative configurations contact Sales Packing and Marking Information: www.intel.com/content/www/us/en/programmable/support/quality- and-reliability/packing.html Page 2 15612 April 2, 2020 Rev B
