As a DC-DC power system designer, you will be driving innovative power circuit designs and system level partitioning from concept investigation and design thru successful product level implementation. Participate in core architecture investigation while working closely with system and power architects by arbitrating design options with technical rigor for key power metric performance optimization including but not limited to efficiency, power density, cost, reduced carbon footprint and scalability. New power architectures definition for computers CPU/GPU and peripherals multi-phase/single phase dc-dc voltage regulators. Deep knowledge of IMVP/VRM regulators is a requirement. Provide single/multiphase DC-DC concept design simulation, calculation and analytical models for prediction of design concept outcome including control loop stability, transient responses, layout analysis and parasitic extractions. Own circuit design for CPU/GPU and peripheral power including circuit schematic and BOM; work with PCB layout team for DC-DC. You should be able to use schematic capture, BOM generation and Spice based simulation tools. Work closely with computer system HW team for DC-DC power designs integration, simulations and system level validation. Work with DC-DC power vendors including silicon and magnetic vendors. Drive continuously highest integrations and technologies innovations. Provide prototypes test and validation results, document multi-dimensional activities. Hands-on work in lab is a plus. Perform competitive bench marking. Provide technical support for production issues debug and resolutions. Conduct DC-DC power seminars and training for multi-functional teams. Spearhead innovation thru exemplary behavior and collaboration. Deep understanding PMIC definition, application or design. Technically lead engineers in the DC-DC team throughout the life cycle of the products from concept to mass volume production.
