Manufacturer of microcontroller solutions, Atmel has introduced a series of multi-string LED drivers that are suitable for solid state lighting and backlighting markets. The LED drivers provide design engineers lesser bill of material, user programmability, scalability across an array of power levels, versatile dimming options, and an efficiency optimizer technology.
These characteristics enable the drivers to suit LED applications in avionics, military, and industrial displays. They are also suitable for PC monitors and edge-lit LCD TVs and general illumination applications.

The drivers’ efficiency optimizer technology reduces power consumption and enables designers to utilize any AC-to-DC or DC-to-DC converter topology with non-isolated or isolated implementation. The technology also dynamically maintains high system power efficiency by reducing excess voltage across LED strings.
The drivers allow LCD televisions to attain low motion blur and high dynamic contrast. They offer a pulse-width modulation of more than 10000:1 for industrial displays and PC monitors. The company’s microcontrollers and LED driver ICs enable networked lighting, color-mixing, and white-point setting with DALI and Zigbee standards. The drivers incorporate complete programmability, LED thermal control and aging, and fault management.
The LED drivers come with a combined power controller for military, medical, and industrial displays and PC monitors. They are also available with internal MOSFET current sinks for low-power LED lighting and direct backlighting applications and external MOSFET current sinks for edge backlighting and high-power LED lighting applications.
