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.

TK6593x

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.
