• Evaluate 12 V, 48 V and alternative power architectures

• Design multiphase VRMs for high current core rails

• Define phase count, magnetics, controllers and power stages

• Design auxiliary rails, analog supplies and protection circuits

• Own schematic design and power layout requirements

• Define sequencing, telemetry and power control interfaces

• Support PMBus, AVSBus and PWM VID control

• Define transient, droop and voltage slew requirements

• Own OCP, OVP, UVP and thermal protection strategy

• Support hardware, firmware and BMC throttling behaviour

• Validate efficiency, ripple, transient response and thermal performance

• Work with power integrity teams on PDN impedance and decoupling

• Coordinate with mechanical, thermal and component vendors

• Automate validation and analysis where applicable

Requirements

• 8+ years of power delivery design experience
