Infineon Introduces High Power LED Switch Mode Driver Portfolio

Infineon has once again expanded its portfolio of switch mode drivers for high power LEDs for general lighting applications. Samples and demo board starter kits are available now in all ILD series and are in volume production.

The new ILD family includes LED driver ICs with integrated power stage and external MOSFETs - up to 98% drive efficiency for a wide range of general lighting applications, including MR16 halogen upgrades, residential and commercial lighting, architectural lighting and street lighting. In addition to the large output current range, Infineon's new ILD series offers customers a high degree of flexibility by using two different dimming methods – analog and PWM (Pulse Width Modulation). In addition to the universal overcurrent protection, the new ILD series drivers also have over-temperature protection to prevent thermal over-stress of LEDs and LED driver ICs, maximizing the service life of LED lamps and LED lamps.

With a wide input voltage range: ILD4001 (4.5 V to 42V) and ILD4035 and ILD4120 (4.5V to 40V), the series can be flexibly combined with most standard power supplies. Dimming can be achieved by PWM via a microcontroller or by analog control voltage.

Like all other Infineon LED drivers, Infineon offers comprehensive design support, including demo boards, application notes and online design tools – from part selection to reference design generation, validation and BOM (bill of materials) creation. use.

Eliminator

The eliminator is a kind of Printer Accessories.

The cartridge is irradiated by laser beam to adsorb toner, and then the toner is hot pressed by fixing roller for printing. In this process, there will be part of toner residual, which can not be "granules returned to the warehouse"; Automatic cleaning function is not adsorbed new toner particles and directly print, will remain toner away, fully ensure the next printing effect. And the Plate-Grid plays an important role. When high voltage generator to a high voltage electrode, wire electrode with reseau formed between a strong electric field, and release the corona, wire electrode and the photosensitive drum ionizes the air between the air ions migrate to the drum surface, make the photoconductor (drum) surface is full of charge, so can spare toner "adsorption to warehouse", so as to save toner, The purpose of reducing environmental pollution.
