Electroluminescent EL lamps and integrated circuit IC drivers

DUREL was formed as a joint venture of 3M and Rogers Corporation, and pioneered Electroluminescent  EL  Lighting  as a viable consumer product. In 2003, DUREL became a wholly owned subsidiary of Rogers Corporation. In 2011, Rogers decided to cease its lamp manufacturing operations, and DUREL was reorganized to focus on their highly successful line of industry leading IC inverters for driving EL lamps and EL wire.

We developed our first DUREL high voltage electroluminescent EL IC driver in 1993, in response to our customers need to have one company provide the entire EL lighting solution both the lamp and the power supply. Since then, Rogers has developed an extensive line of these high performance devices. Using our proprietary circuit design, we achieve low-noise performance for applications that are sensitive to electrical and audible noise.

Quality is a Rogers hallmark. All DUREL IC drivers are RoHS and WEEE compliant.

We serve customers in a broad range of industries. Rogers DUREL IC drivers are the products of choice for designers in appliance, automotive, consumer electronics, portable communications, residential and commercial lighting, and transportation industries.

We have built our reputation on designing and manufacturing products that exceed our customers expectations.

We serve customers around the globe through our manufacturing facilities, sales and customer support organizations in Asia, Europe, and North America. Our manufacturing and warehouse facilities are strategically located to provide you with prompt, reliable access to Rogers products.

Electroluminescent Lighting and Drivers. Electroluminescent lighting is achieved by using an EL lamp which is a piece of plastic material coated with a phosphorous.

The MIC4833 from Micrel is a low noise dual Electroluminescent EL Panel driver used in backlighting applications.

The MAX14514 is a high-voltage DC-AC converter ideal for driving two electroluminescent EL lamps. The MAX14514 features a 2.7V to 5.5V input range that allows the device to accept a wide variety of voltage sources, including single-cell lithium-ion Li batteries. The lamp outputs of the device generate up to 300VP-P for maximum lamp brightness.

The MAX14514 utilizes an inductor-based boost converter to generate the high voltage necessary to drive EL lamps and allows the use of a 220µH inductor to effectively drive total combined lamp sizes of up to 20nF.

The MAX14514 uses a high-voltage full-bridge output stage to convert the high voltage generated by the boost converter to an AC waveform suitable for driving the EL panels. An external resistor controls the slew-rate of the rising and falling edges of the AC drive waveform to reduce audible noise output. The high-voltage outputs are ESD protected up to 15kV Human Body Model, 4kV IEC 61000-4-2 Air Gap Discharge, and 4kV IEC 61000-4-2 Contact Discharge.

The MAX14514 features dimming/enable controls DIM1, DIM2 for each output to allow the user to set the peak-to-peak output voltage with a PWM signal, a DC analog voltage, or a resistor connected from DIM_ to GND. The MAX14514 also provides a slow turn-on/-off feature that slowly ramps the output voltage applied to the lamp when enabled or disabled.

The MAX14514 enters a low-power shutdown mode when the EN and DIM_ inputs are connected to GND. The device also features thermal shutdown if the die temperature exceeds 158 C typ.

The MAX14514 is available in a space-saving, 14-pin, 3mm x 3mm TDFN package and is specified over the extended -40 C to 85 C operating temperature range.
