The LT3519 can drive up to ten 100mA white LEDs from a 12V input, making it ideal for a variety of applications such as automotive and industrial lighting. It can deliver efficiencies up to 90% in boost mode from a compact MSOP-16E package. The LT3519 utilizes True Color PWM™ dimming to deliver constant LED color with ranges of more than 3,000:1. For less demanding dimming requirements, the CTRL pin can be used to offer 10:1 analog dimming. The device’s fixed frequency, constant current, constant voltage regulation provides stable operation over a wide range of supply and output voltages, while ensuring uniform brightness of LEDs. There are three switching frequency options available: the LT3519, which switches at 400kHz; the LT3519-1, which switches at 1MHz; and the LT3519-2, offering a 2.2MHz switching frequency, enabling designers to optimize efficiency while minimizing external component size.

The LT3519 senses output current at the high side of the LED, enabling buck, buck-boost or boost configurations. Combining a traditional voltage feedback and unique floating current sense feedback, these converters can operate as constant voltage or constant current source, offering maximum design flexibility. Other features include open LED protection, soft-start and thermal protection.Belgium from September 23rd-26th will see the unveiling of the first application of UV LED Curing technology for a flexographic label press. The system is designed and developed by Phoseon Technology and based on Phoseon's RX FireFlex architecture. Phoseon's UV LED curing technology will be shown in association with press maker Gallus (Hall 5, B50) with newly developed UV LED curable inks provided by Siegwerk (Hall 12, V70) and will be seen in action on the new Gallus ECS 340 press.
This product showcase is a precursor of a range of UV LED curing systems from Phoseon Technology designed specifically with the UV Printing press market in mind including applications in flexography, sheetfed offset and web offset. These products will be available as a capable and cost effective alternative to existing traditional UV Curing systems using mercury vapor lamp technology and will include Phoseon's patented SLM technology that allows for maximum UV performance.Phoseon's patented Semiconductor Light Matrix (SLM) technology combines a dense array of light emitting semiconductor devices (UV LED), with high tech micro optics and micro cooling in a cost-effective MOEMS (micro opto electro-mechanical system) package. Phoseon's solutions have significant advantages in energy usage, reduced heat load to the substrate, smaller equipment footprint and a true earth friendly "cleantech" solution that does not require the use of mercury and produces no ozone. These advantages, and others, are all available at comparable cost of ownership to existing solutions.
