LYTSwitch-1 LED Driver ICs From Power Integrations Reduce Complexity in Bulbs, Tubes and Ballasts up to 22 W
2016-06-08 | ReturnDownload this Press Release (PDF)
High PF, low THD LED driver ICs set a new standard in efficiency
SAN JOSE, Calif.--(BUSINESS WIRE)-- Power Integrations (Nasdaq: POWI), the leader in high-efficiency, high-reliability LED driver ICs, today announced its LYTSwitch™-1 single-stage, non-isolated, buck topology LED driver IC family. Featuring a very compact footprint, the IC enables the design of LED bulbs and tubes with high constant-current accuracy while using a minimum number of components. A novel driver algorithm ensures high power factor (PF) and low total harmonic distortion (THD) while maintaining very high efficiency.
This Smart News Release features multimedia. View the full release here: http://www.businesswire.com/news/home/20160608006434/en/
Housed in a compact SO-8 package, LYTSwitch-1 ICs are greater than 93% efficient with a PF of over 0.9 and THD as low as 15%. Devices can be used in a low-side buck topology for reduced EMI or in a high-side buck topology which simplifies design. Delivering up to 22 W without a heatsink, the universal input (100 - 308 VAC) ICs incorporate a 725 V MOSFET for high reliability. Designers can make use of small, off-the-shelf inductors due to a unique peak current control algorithm. The new devices meet all applicable international standards including: DOE 6 (external power supply), CEC Title 20 and 24, ENERGY STAR® SSL, EN61000-3-2 (C) plus China and India standards.Comments Hubie Notohamiprodjo, director of product marketing at Power Integrations: “Low system complexity and high performance make LYTSwitch-1 ICs ideal for both commercial and residential lighting applications. The low component count and compact size make these LED driver ICs easy to fit into space-challenged applications such as tube end caps, small form factor candles and GU10 bulbs, as well as low cost A19 and decorative-filament lamps.”
In common with all Power Integrations products, LYTSwitch-1 LED driver ICs have a host of protection features including thermal foldback with end-stop shutdown, short circuit protection, input and output OVP, overcurrent and SOA protection.
LYTSwitch-1 IC samples are available now. Devices are priced at $0.26 in 10,000-piece quantities. Reference design DER-548 is available for download now from the Power Integrations website at https://www.power.com/lytswitch-1.
