	Description:		Chris and Carmen have both been co-hosts of The Engineering Commons and both wrote on EngineerBlogs.org Carmen is a Staff Application Engineer at Renesas, in the division that used to be Intersil Field Application Engineers (FAE) vs Application Engineer (AE) The chips Carmen works on help power Intel / AMD processors AE vs Silicon designer Regulators TDP – Total Dissipated Power Core rail – 200A over short timelines (!) Intel proprietary bus is called SVID Multi-phase regulators can have up to 8 buck converters in line Slewing current is still limited to V = L * dI/dt AMD processors have proprietary buses called SVI2 or SVI3 Many of these chips provide telemetry (temperatures at various points, current draw, etc) Carmen doesn’t want to make 12 layer eval boards because most customers wouldn’t be able to implement that sort of thing Taller inductors are better Processors throttling themselves Battery upstream Parasitics DrMOS Driver is needed to drive MOS with significant current Voltage vs current mode control “Virus mode” is a stress test that Intel specs Performance tuning with digital PMBus App notes People Carmen follows on Signal Integrity Journal Steve Sandler Eric Bogatin Istvan Novak Past training materials that are easy to find SLVA882B – Multiphase Buck Design From Start to Finish (Part 1) Power Supply Design Seminar Voltage regulator design and optimization for high-current, fast-slew-rate load transients Carmen has been simulating using Cadence Sigrity Connect with Carmen on LinkedIn
