Package
EL Panel A Enable Pin: Logic high enables ELA and logic low disables ELA output.
RSW pin: Sets internal boost converter switch frequency by connecting an external
resistor (R
EL Panel B enable pin: Logic high enables ELB and logic low disables ELB output.
Ground.
Switch Node: Drain of internal high-voltage power MOSFET for boost circuit.
Regulated Boost Output: Connect to the output capacitor of the boost regulator and
to the cathode of the diode.
EL output: Common EL output terminal to both ELA and ELB. Connect one end of
each EL panel to this pin.
EL Panel B output: Connect the other end of the EL panel B to this pin.
Pin Function
DC Input Supply Voltage: 2.3V to 5.8V
EL Panel A output: Connect the other end of the EL panel A to this pin.
