TK6592x
The oscillator circuits for the boost converter and lamp
driver are both internally generated in the TK6592x, 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 TK6592x 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 TK6592x is available in a miniature, 6-pin
SOT23L-6 surface mount package

DESCRIPTION
The TK6592x 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 TK6592x 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.
