Supertex' new HV835 and HV857L low noise electroluminescent (EL) lamp driver ICs are designed to drive EL lamps for handheld devices such as mobile phones, PDAs, global positioning systems, and other handheld wireless products. The HV835 is a dual segment EL lamp driver that features independent input control for lamp selection, peak-to-peak output of 160 V, and a wide input supply range of 2,0 V to 5,8 V, for driving two EL lamps with a combined area of 22,6 cm². The HV857L is a high voltage driver designed to drive a single EL lamp of up to 32,3 cm². The IC features patented circuitry for reduced audible noise, peak-to-peak output of 190 V for higher lamp brightness.
