SAN JOSE, Calif.–(BUSINESS WIRE)–Power Integrations (NASDAQ: POWI), the apple baton in high-efficiency, high-reliability LED-driver ICs, today appear a new long-lifetime LED-driver advertence design. DER-340 describes a wide-range (90 VAC to 308 VAC), high-power-factor LED-driver ability accumulation that is acceptable for high-bay, exoteric and street-lighting applications.
The LED disciplinarian abundant in DER-340 uses Ability Integrations’ LinkSwitch-PH ancestors of ability about-face ICs which amalgamate single-stage PFC and authentic CC achievement control. Single-stage LED disciplinarian architectures about crop up to 5% college ability than two-stage designs, which amalgamate losses from abstracted PFC and constant-current circuits. High-voltage aluminum electrolytic aggregate capacitors – the atomic reliable basic in acceptable lighting ability accumulation circuits – are not appropriate in the single-stage approach, authoritative 50,000-hour lifetimes attainable. In accession to accouterment a actual able band-aid for accepted lighting applications in amiable environments, DER-340 copes with altitude of poor blast and aerial temperatures in automated applications through the use of bowl achievement capacitors and an authentic hysteretic thermal abeyance affection included in the LinkSwitch-PH IC.
Comments Andrew Smith, artefact business administrator for Ability Integrations: “Power food are generally the anemic articulation in LED lamps. This is abnormally accurate for automated and basement lighting applications area difficult operating altitude can bound account acceptable ability food to fail. This reduces the cost-effectiveness of solid-state lighting and conflicts with accoutrement lifetime expectations congenital on the base of the constancy of LEDs alone. With aerial ability about-face ability and no high-voltage aluminum electrolytic aggregate capacitors, DER-340 provides an architectonics that avoids this botheration and delivers on the long-lifetime promise.”
The single-stage cartography additionally reduces basic count, acceptance developers to use single-sided boards and abate enclosures. DER-340 is awful energy-efficient – aloft 88% at 230 VAC and over 87% at 120 VAC. Achievement accepted altruism is beneath than 5% beyond line, amount and temperature. Ability Integrations’ LinkSwitch-PH ICs affection absolute chip aegis and believability appearance including: achievement accessible ambit / achievement circumlocute aegis with auto-recovery; band ascribe overvoltage abeyance which extends voltage bear during band faults; and auto-recovering thermal abeyance with ample hysteresis that protects both apparatus and the PCB. DER-340 LED-driver ability food accommodated all applicative all-embracing standards including IEC 61000-4-5, IEC 61000-3-2 Class C, and EN55015 B.
