an easy to use user interface LED driver

Energy and maintenance savings are equally as important as first cost in creating a sustainable solution," Mr. Kaveski continued. "Because our LED Parking Garage solution can pay for itself and generate significant savings over its long life even without considering rebates, we expect the strong interest we've received from pre-viewing the new line of fixtures with customers only to increase as the government's stimulus projects come on line later this year. In particular, we believe by offering an LED solution that's both affordable and efficient that we've addressed GSA Acting Administrator Paul Prouty's February call to convert parking garages to LED lighting."

YAHAM is a leading supplier of energy solutions and the world's only supplier of EFO(R), a lighting technology that is more efficient than conventional electric lamps. Energy Focus products are designed, manufactured and marketed for the commercial lighting and swimming pool markets. Energy Focus solutions provides energy savings, aesthetic, safety and maintenance cost benefits over conventional lighting. Customers include supermarket chains, retail stores, museums, theme parks and casinos, hotels, swimming pool builders and many others.A global designer and manufacturer of analog ICs for communications, industrial, medical and automotive applications, expands its comprehensive LED driver portfolio with the AS1115, an easy to use user interface LED driver. The AS1115 combines display driving and key scanning to provide a complete front panel solution which eliminates the use of secondary μP or other logics plus discrete devices, reducing BOM count and cost.

The AS1115 can drive either eight 7-segment digits or 64 individual LEDs with 47mA per digit or 5mA per LED. An external resistor can easily adjust the current. With an excellent accuracy of ±3%, the AS1115 improves picture quality for LED displays, this is due to minimised intensity variations between the LEDs and LED modules. For either global digital brightness control, or separate dimming, of each single digit a 4-bit PWM is implemented. Additionally the AS1115 offers the read back of up to 16-keys completing the single chip UI solution.
