Atmel introduces power efficient, multi string led drivers
1 min read
Atmel has released a new series of 'intelligent' multi string led drivers for the backlighting and solid state markets.
The devices feature efficiency optimiser technology, flexible dimming options, user programmability and scalability across a range of power levels. They are designed for led applications in direct and edge lit lcd tvs, pc monitors, industrial, military and avionics displays. They are also suitable for general illumination in the commercial, industrial and infrastructure market segments.
The led drivers incorporate Atmel's patent pending efficiency optimiser technology, which is designed to minimise power consumption to the lowest practical level. According to the microcontroller specialist, this technology allows designers to use any dc/dc or ac/dc converter topology with isolated or non isolated implementation, whilst minimising excess voltage across led strings.
Optimised to enable lcd tvs to achieve 10M:1 dynamic contrast and the lowest motion blur, the drivers are also designed to provide more than 10000:1 PWM dimming range for pc monitors and industrial displays. Other features include comprehensive fault management, led ageing and thermal control.
"Atmel is excited to enter some of the fastest growing segments in the semiconductor industry," said Tushar Dhayagude, marketing director of smart power products at Atmel. "Increasing led adoption in lcd panels and lighting creates a tremendous opportunity for Atmel to leverage its industry leading microcontroller architectures to push the envelope on efficiency, programmability, simplicity and solution cost."
