D392A EL lamp driver
The Durel division of Rogers Corporation has announced the latest addition to its high-performance electroluminescent (EL) lamp driver integrated circuits (ICs).
The D392A EL lamp driver delivers the programmable output voltages needed to power a range of EL lamps, including in portable applications such as cellular telephones, data organisers and personal digital assistants (PDAs), remote controls, monochrome LCDs and DFLX EL keypad lamps.
Operating with supply currents ranging from 16mA to 35mA and a minimum enable voltage of 1.3V, the high-efficiency EL lamp driver generates typical peak-to-peak output voltages of 170V to 230V, with a maximum rating of 250V 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.
Durel's D392A EL lamp driver, which supports a range of lamp frequencies, incorporates a dimming feature that can be controlled through discrete components, an analogue voltage or a PWM signal.
The robust lamp driver IC features a high +/-15 kV ESD (human body model) rating and output over-voltage protection for high reliability in a range of applications.
The lamp driver is compatible with external clocks and is supplied in a 'green' RoHS-compliant (lead-free) 14-pin DFN package.
The D392A lamp driver IC can be implemented in most practical circuits with low-profile inductors and a few other passive components.
In addition, designers' kits for the D392A, complete with evaluation boards, are also available.
The lamp driver IC is rated for operating temperatures from -40C to +85C and storage temperatures from -55C to +150C.
