LED General Illumination (Off-line:Non-isolated)

To ensure the lowest system cost, engineering teams working on off-line led lighting for general illumination challenge the needs of non isolated solutions which greatly simplify the design and the production of magnetic components. Along the wide spectrum of applications, ranging from the LED retrofit bulb to LED street lighting, STMicroelectronics offers a wide range of products and solutions for non isolated topologies. In particular, the power stage architecture, with or without power factor correction is controlled in order to get the highest efficiency, and the voltage and current regulation is performed with superior accuracy in order to guarantee precise light intensity.
