Infineon push general lighting dedicated high power LED driver

AG (Infineon Technologies) for general lighting applications, the introduction of high power LED switched LED drive products. The new driver combines the over temperature protection function to support the 350mA to the output current range of a few amps, which helps to prolong the service life of the LED, and provides an economical and effective solution for high efficiency indoor and outdoor lighting equipment.

The new ILD series of products including LED driver IC and integrated power level (power stage) or collocation external MOSFET, can improve the general lighting equipment (such as: modified MR16 halogen lamp, residential and commercial lighting, building lighting equipment and lamps etc.) the drive efficiency to 98%. In addition to supporting a high output current range, ILD series products can also be analog and PWM (pulse width modulation) two different dimming mode, to provide customers with a high degree of flexibility.

In addition to providing overcurrent protection widely, while supporting the ILD driver over temperature protection, the protection of LED and LED driver IC from over temperature, and then extend the LED lamp and LED lamp life.

Infineon DC-DC driver LED general lighting applications department director Hakan Yilmazer said: "the launch of the new ILD series products, to meet the whole Infineon (low, high power LED, Gao Jichao) at the same time meet the design demand, provide affordable products and best performance. LED technology is a revolutionary change in the lighting industry, is in line with Infineon's vision for improving energy efficiency with electronic components. "

Market research firm Strategies Unlimited estimates that in 2011 the global LED lighting drive IC sales will reach 227 million. According to market experts pointed out that the global lighting LED drive IC market will grow from $114 million 700 thousand in 2011 to $585 million 400 thousand in 2015, the annual compound growth rate (CAGR) of more than 50%.

ILD series of products designed for specific LED current or equipment, can achieve a high cost benefit. For example, ILD2035 is designed for use with 1W MR16 halogen lamp LED. Another good example is the ILD4001, whose features and protection functions are built on an independent LED controller, and use the external MOSFET as the power level. ILD4001, ILD4035 and ILD2035 three devices will use a very small SC-74 package, the fourth device ILD4120 is exposed pin DSO-8 package.

ILD series products have a wide input voltage (ILD4001 4.5 V to 42V, ILD4035 and ILD4120 is 4.5V to 40V), and can be flexibly matched with most standard power supplies. And can be used to control the voltage pulse width modulation (PWM) through microcontroller or analog control, the establishment of dimming function.

Infineon all LED drives also provide support for a wide range, including a description of the demonstration board, application, and can be used in the selection of parts, design and verification to establish reference material list (BOM) online design tool.
