Stress Analysis
Upowertek performs stress analysis in the DVT stage and output reports for every product platform. All the LED drivers are designed with conservative margin.

MTBF Calculation
MTBF Calculation: MIL-HDBK-217
Software: Relcalc 217F2

Lifetime Calculation
Among all the components in an LED driver, the bulk electrolytic capacitor has the shortest life, so it determines the life of the whole device

- k is the factor determined by capacitor’s RMS ripple current and operating voltage, it is provided as either a value or a function,
- L0 is the lifetime value tested in standard condition provided in the datasheet,
- Ts is the rated case temperature,
- Ta is the operating case temperature.
