TK6591x
SUPPLY PIN (V
CC
)
This pin is the positive input supply for the TK6591x. Good design practices dictate capacitive decoupling to the ground
pin.
GROUND PIN (GND)
The pin provides the ground connection for the IC.
IND PIN
This pin is periodically pulled to ground by a power transistor acting as an internal switch to the TK6591x. Externally, this
pin is typically connected to an inductor and a rectifying diode. By modulating the switching action of the internal switch,
the TK6591x can boost the relatively low voltage of the battery to the high voltage required to drive the EL Lamp.
HV PIN
This pin is connected to the filter capacitor and the cathode of the rectifying diode in order to generate a high voltage
supply. This high voltage supply is switched to the terminals of the EL Lamp through the H-Bridge.
EL
+
PIN
This pin is connected to one side of the EL Panel.
EL
-
PIN
This pin is connected to the other side of the EL Panel.
Note:
Measuring the voltage across the EL lamp (EL
+
pin to EL
-
pin) should be done with balanced scope probes using
differential measurement techniques to obtain a true waveform of the voltage across the EL lamp.
