Define input ranges, load profiles, thermal limits, and regulatory requirements.
Step 2
Architecture & Simulation
Evaluate topology choices and validate performance via circuit and thermal analysis.
Step 3
Design & Prototyping
Create schematic and layout with PI and EMI best practices, then build and bring up prototypes.
Step 4
Validation & Handover
Run efficiency, thermal, stress, and compliance checks before production support and release.
Frequently asked questions.
Do you design both isolated and non-isolated converters?
Yes. We deliver isolated flyback, forward, and LLC-derived solutions as well as non-isolated buck, boost, and buck-boost topologies based on your efficiency, safety, and cost targets.
Can Qmax optimize designs for low EMI and certification readiness?
Absolutely. We apply EMI-aware component selection, switching strategy tuning, filter design, and PCB layout best practices to reduce emissions and accelerate pre-compliance testing.
Do you support high-current rails for AI and compute hardware?
Yes. We build high-current, low-noise multi-rail PDNs for GPUs, CPUs, and FPGA platforms with tight voltage regulation and transient response requirements.
Can you help with legacy power supply redesigns?
We frequently modernize aging designs by improving efficiency, thermal behavior, and manufacturability while preserving interface compatibility and field constraints.
