Job Description
Digital Multiphase Controllers and Smart Power Stage Modules are essential components for delivering high & precise power requirements of the CPUs/GPUs used in data centers and AI hardware modules. A single Controller can control up to 32 SPS modules to form a Buck converter that can supply in excess of 2500A to a 0.9V input.
Controllers have many highly customizable features, some of which include:
Support up to 4 rails per controller
Faults & Warnings for Temperature, Voltage, Current
Multi-layer Protection circuitry to have the controller work in a well-defined boundaries
Telemetry for monitoring Internal/External Temperature, Input/Output Current/Voltage/Power
Flexible phase assignment & ability to auto add/drop
Ability to adjust Load & Line per output current demands
Highly customizable loop tuning to address various system needs
Internal digital scope & black box for fault & functionality debugging
Multiple communication interface support: PMBUS, AVS, SVID, SVI3, PWMVID
Compliance to Intel, AMD, HPE, Microsoft, Google, Nvidia requirements
Validation tasks aim to verify that all features and functions of the controllers are working according to Industry requirements as well as to internal design specifications.
The validation will cover the complete performance of the controller, both functionally & parametrically. It will be broken into several tasks to ensure all features are fully functional and all parametric performance is within limits as stated in the datasheet. Any bugs found during this time frame will be promptly reported & debugging process will start. Qualitative data collection & reporting is to be provided before the non-flexible deadlines.
If required, support will be provided to other disciplines, such as design, firmware, GUI, test engineering, etc. Test program to bench correlation will be conducted on select parameters and trimmings.
The validation tasks will cover all aspects of the Controller development flow. The candidate is expected to support the variety of validation tasks from the list below while working along the other team members and/or individually:
Evaluation Plans
Python Scripting
Hardware Automation
Evaluation & data collection
Comparison against specification & simulation expectations
Debugging
Data analysis & Reporting
ATE to Bench Correlation
Environment
You will join a multinational team of engineers responsible for validation and development within Performance Core Power division of Power Business Unit of Renesas Design Germany GmbH under the Renesas Electronics Corporation umbrella. The team located in Germering provides its expertise and services to multiple teams in Europe, US and Asia.
Qualifications
The successful candidate is expected to have solid background in electronics and power circuits and very keen interest in research and development. Experience with measurement equipment is a must have. Candidates are expected to be excellent communicators and have solid presentation skills.
Candidates matching this outline in Electrical Engineering or similar are welcome to apply:
Studied electronics with focus on mixed-signal and switching supplies

Studied about semiconductors for Power Management & key performance metrics
Laboratory measurements skills (Oscilloscope, DMM, sourcemeter, function generator, etc.)
Good analytical & debugging capabilities with R&D mindset
Understanding of bench automation
Programming/Scripting skills (Python)
Printed circuit Board Schematic & Layout design is a plus
Readiness to work in a multicultural team
Fluent in verbal & written English
