LakeSemi's production-ready power solution library — every solution ships with a complete BOM, schematic and PCB reference design, transformer parameters, and measured efficiency and EMC data. Customers can take it straight to production. Built on QST GaN combo power ICs and companion controllers, covering everything from fast-charging adapters to industrial power supplies.
Four power-level reference designs, all built on LakeSemi's own silicon, with live status labels. Click a chip tag to jump to its product page.

LakeSemi solutions are not eval-board demos — they are fully engineered, production-ready reference designs with six deliverables handed over at once.
All power devices, magnetics and passives specified at once, with LakeSemi chips covering the full chain.
Layout optimized for EMC; Gerber files ready for direct production.
Measured conducted and radiated emission curves ship with the solution — reuse our rectification experience.
Winding structure, air gap and core selection fully documented — ready to purchase and build.
Typical-load efficiency curves and key-device temperature rise — design margins at a glance.
Full technical support from prototype debug to pilot production, with on-site response.
A five-step production support process with the LakeSemi FAE team engaged at every step.
Lock the solution and chip set by power level and use case
Hands-on Demo Board evaluation; verify efficiency and thermal data
Pre-testing and rectification guidance to pass certification
Customer line bring-up with on-site process support
Stable chip supply with capacity and lead-time assurance
