1 / 16 page May 2000 TOKO, Inc. Page 1 TK6593x The oscillator circuits for the boost converter and lamp driver are both internally generated in the TK6593x, 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. 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. The TK6593x is available in a miniature, 6-pin SOT23L-6 surface mount package. HV VCC EL+ IND GND HV BOOST CONTROL H BRIDGE OSCILLATOR EL- HV VCC IND EL- GND EL+ BLOCK DIAGRAM 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. 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 battery voltage. This architecture allows the output voltage to remain relatively constant as battery voltages decay, without the need for directly sensing the high voltage output of the EL driver.
