DESCRIPTION The TK6593x Electroluminescent (EL) Lamp Driver has been optimized for battery controlled systems where power consumption and size are primary concerns. The miniature device size (SOT23L-6), together with the miniature Toko EL coils (D32FU, D31FU, D52FU), further helps system designers reduce the space required to drive the small EL panels. FEATURES ■ High Ratio of Brightness / Input Power ■ Constant Brightness Versus Input Supply Changes ■ Optimized for 15 nf to 45 nf Panel Capacitance ■ Panel Voltage Slew Rates Controlled for Life Enhancement ■ Panel Peak to Peak Voltage Independent of Input Voltage and Temperature ■ Panel Peak to Peak Frequency Independent of Input Voltage and Temperature ■ Miniature Package (SOT23L-6) ■ Operates with Miniature Coil ■ Minimum External Components ■ Laser-Trimmed Fixed Frequency Operation ■ PWM Control Method ■ Adjustable Output Voltage ■ Lower Noise (Audio and EMI) ■ Intensity Control Application (Refer to Application Information) APPLICATIONS ■ Battery Powered Systems ■ Cellular Telephones ■ Pagers ■ LCD Modules ■ Wrist Watches ■ Consumer Electronics
