How to ensure the quality and reliability of LED drivers?

(1) Standardized professional design process control: technical pre-research, feasibility assessment, preliminary design, detailed design, engineering prototype, small batch trial production. (2) Reasonable component design margin (3) Selection of high-quality components: electrolytic capacitors, ICs, power semiconductors, magnetic components, etc. (4) Strict quality verification and testing procedures : stress analysis, EVT, SVT, DVT and other tests and MTBF calculations and experimental verification.
