TK6593x  
LARGE EL LAMP DRIVER  
FEATURES  
APPLICATIONS  
■ High Ratio of Brightness / Input Power  
■ ConstantBrightnessVersusInputSupplyChanges  
■ Optimized for 15 nf to 45 nf Panel Capacitance  
■ Panel Voltage Slew Rates Controlled for Life  
Enhancement  
■ Battery Powered Systems  
■ Cellular Telephones  
■ Pagers  
■ LCD Modules  
■ Wrist Watches  
■ Panel Peak to Peak Voltage Independent of Input  
Voltage and Temperature  
■ Consumer Electronics  
The oscillator circuits for the boost converter and lamp  
driverarebothinternallygeneratedintheTK6593x,without  
the need for external components. The clock frequency of  
the boost converter is laser-trimmed to ensure good initial  
accuracy that is relatively insensitive to variations in  
temperature and supply voltage. The clock frequency of  
the lamp driver tracks the frequency of the boost converter  
by a constant scaling factor.  
■ 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  
Furthermore, the drive architecture of the TK6593x has  
been designed to limit peak drive current delivered to the  
lamp. This approach limits the slew rate of the voltage  
across the lamp and has the potential to improve lamp life  
and decrease RF interference.  
■ Lower Noise (Audio and EMI)  
■ Intensity Control Application (Refer to Application  
Information)  
DESCRIPTION  
The TK6593x Electroluminescent (EL) Lamp Driver has  
beenoptimizedforbatterycontrolledsystemswherepower  
consumptionandsizeareprimaryconcerns.Theminiature  
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.  
The TK6593x is available in a miniature, 6-pin  
SOT23L-6 surface mount package.

The proprietary architecture (detailed in the Theory of  
Operation section) of the TK6593x provides a constant  
output power to the lamp, independent of variations in the  
batteryvoltage.Thisarchitectureallowstheoutputvoltage  
to remain relatively constant as battery voltages decay,  
without the need for directly sensing the high voltage  
output of the EL driver.
