About the role
Power Integrations is seeking a Staff Applications Engineer (Datacenter) to define and develop high-density power solutions for AI and data center applications. You will develop high-density power converters, intermediate bus converter (IBC) modules, and protection circuits using GaN and silicon technologies.
What you'll do
- Develop high-frequency power converter solutions for AI and data center applications across AC/DC and DC/DC architectures using Power Integrations products.
- Define power converter architectures and key system components for emerging AI and data center power solutions.
- Provide switching power supply design support and technical guidance for customer applications worldwide.
- Develop reference designs and application solutions demonstrating performance, efficiency, and system value for AI and data center power architectures.
- Collaborate with product development teams and customers to evaluate design tradeoffs and optimize system performance, density, and reliability.
What you'll need
- Bachelor’s or Master’s degree in Electrical Engineering, or foreign equivalent.
- Minimum 8-12 years of relevant industry experience.
- Hands-on experience and expertise in high-density, high-frequency power converter design, including server power applications above 3 kW.
- Experience designing high power and high current planar transformers, along with expert knowledge of high-frequency magnetics design.
- Strong familiarity with power supply topologies including Totem pole PFC, Vienna Rectifier, Phase-shifted and LLC resonant converters, and buck, boost, buck-boost, and flyback converters.
- Experience with MATLAB, Excel, and simulation software including SIMPLIS, LTspice, or PLECS, paired with hands-on lab equipment testing for high-frequency switching power supplies.
- Ability to perform complex calculations, including worst-case analysis, and author specifications, technical reports, and test plans.
Nice to have
- Experience developing firmware in C/C++ for embedded controllers in power supply applications and providing firmware guidance.
- Experience using finite element tools such as ANSYS.
- Experience designing power supplies/power converters from concept to production and supporting post production.
- Knowledge of communication protocols such as I2C and PMBus.
- Familiarity with tools for debug of power converters with embedded controllers.
