Power Integrations announced its LYTSwitch-7 single-stage, non-isolated, TRIAC-dimmable, buck topology LED driver IC family. Capable of delivering up to 22 W without a heatsink in a very small SO-8 footprint, these high-efficiency devices are suitable for bulbs, tubes and fixtures.
LYTSwitch-7 designs do not require bleeders; employing simple, passive damping for TRIAC management and an off-the-shelf, single-winding inductor, reducing component count to just 20, as compared to approximately 35 parts for typical dimmable LED driver boards.
The ICs deliver a phase-cut (TRIAC) dimming solution with a wide dimming range and monotonic dimming response. They enable efficiency of greater than 86% – around 2% higher than conventional dimmable products – with high power factor, accurate regulation and comprehensive protection. They suit low- or high-line input as well as wide-range universal-input designs for commercial lighting applications, which operate from 90 V a.c. to 305 V a.c. with TRIAC dimming enabled in low-line installations.
LYTSwitch-7 includes a host of protection features including thermal foldback with end-stop shutdown, which protects the IC, driver and fixture at abnormally high ambient temperatures by automatically reducing the current flow and dimming the lamp. Developers find that thermal foldback is the key to reducing costs associated with over-design of both electrical and mechanical components to meet reliability goals, since the IC automatically limits unusual temperature excursions without extinguishing the lamp. Devices are also protected from open- and short-circuit conditions, input and output over-voltage, over-current and SOA.
Key applications include low-cost A19 lamps, small-form-factor lamps such as candle-style and GU10 bulbs, commercial and industrial applications, ceiling lamps and downlight fixtures. Two reference designs (DER-539 and DER-540) are available for download from the Power Integrations website at https://www.power.com/lytswitch-7.
