1 / 13 page 1 SP4416DS/06 SP4416 Electroluminescent Lamp Driver with 4-Level Light Intensity Selection Feature © Copyright 1999 Sipex Corporation DESCRIPTION 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. s 4-Level, Software Selectable Light Intensity Function s 75%-80%-85%-100% Intensity Level Options s Extends Standby Time & Battery Life when used in Conjunction with Power Management Devices s Requires only 2 External Components: Oscillator Setting Capacitor and Inductor s Low Power +3.3V Operation s 100nA Standby Current s Space-Saving 10-pin µSOIC Package APPLICATIONS s Cellular Phones s LCD Displays & Keypads s PDAs s Handheld Portable Electronic Devices Electroluminescent Lamp Driver with 4-Level Light Intensity Selection Feature SP4416 1 2 3 4 5 6 7 8 9 10 SP4416EU COSC2 COSC1 VSS EL1 CS COIL EL2 VDD VEE ENLI ® |
