The SP4416 is a high voltage output DC-AC converter that operates from a 3.3V battery and generates up to 220V_PP AC output. As with Sipex's other electroluminescent driver products, the AC output is used to generate light in an electroluminescent lamp. The SP4416 incorporates an intensity select feature within the enable circuit so that the user can program the desired light intensity. The SP4416 uses only two external components to generate light; the oscillator capacitor and inductor. The ENLI pin is used for either an enable function or a step-up intensity function. Four light intensities can be set by strobing the ENLI pin in a defined time period. The SP4416 with the intensity function can be used in cellular phone applications, PDA's, and other hand-held CPU controlled equipment.
