SANTA CLARA, USA: Renesas Electronics America Inc., a premier provider of advanced semiconductor solutions, announced the availability of its R2A20134 LED driver IC that supports LED lighting applications with high efficiency and a high power factor at low cost.
The market scale of the LED lighting field is expected to grow substantially, mainly spurred by the adoption of LED lighting as a replacement for incandescent light bulbs. Since LEDs use direct current drive, it is necessary to convert the commercial alternating current (AC) power supply to direct current (DC).
This requirement to add AC-DC conversion circuits has brought to the forefront a demand for elements designed to address issues such as cost, conversion efficiency and power factor. In response, a variety of control methods for LED lighting drivers have been announced.
Using exclusive voltage step-down control technology, Renesas Electronics has succeeded in developing an LED driver IC that delivers high efficiency and a high power factor at low cost.
