This design uses LinkSwitch™-PH which dramatically simplifies implementation of LED drivers and introduces a new control technique that provides very high power factor and accurate output current control.
Features include:
Clean monotonic start-up – no output blinking
Fast start-up (<100 ms) – no perceptible delay Low component count and small printed circuit board footprint solution Summary and Features No electrolytic capacitors Clean monotonic start-up – no output blinking Fast start-up (<100 ms) – no perceptible delay Highly energy efficient o ≥90% at 115 VAC and 230 VAC input Low cost, low component count and small printed circuit board footprint solution o No current sensing required o Frequency jitter for smaller, lower cost EMI filter components Integrated protection and reliability features o Output open-circuit / output short-circuit protected with auto-recovery o Line input overvoltage shutdown extends voltage withstand during line faults. o Auto-recovering thermal shutdown with large hysteresis protects both components and printed circuit board o No damage during brown-out or brown-in conditions Meets IEC 61000-4-5 ring wave, IEC 61000-3-2 Class C harmonics and EN55015 B conducted EMI
