The D392A electroluminescent (EL) lamp driver delivers the programmable output voltages needed to power a wide range of applications, such as cellular telephones, PDAs, remote controls, monochrome LCDs, and EL keypad lamps. Operating with supply currents ranging from 16 to 35 mA and a minimum enable voltage of 1.3 V, the EL lamp driver generates typical peak-to-peak output voltages of 170 to 230 V, with maximum rating of 250 V peak-to-peak. It uses patented wave-shaping technology with slew-rate control to produce clean, low-noise output voltage waveforms for noise-sensitive applications. The D392A EL lamp driver, which supports a wide range of lamp frequencies, incorporates a dimming feature that can be controlled through discrete components, an analog voltage, or a PWM signal. Other features include a high +/-15 kV ESD (human body model) rating and output over-voltage protection for reliability. The lamp driver is compatible with external clocks and supplied in an RoHS-compliant (lead-free) 14-pin DFN package. In addition, designer kits with evaluation board are also available. The lamp driver IC is rated for operating temperatures from -40ºC to +85ºC, and storage temperatures from -55ºC to +150ºC. ROGERS CORP., Rogers, CT. (800) 227-6437.
