Pin Function
Supply (Input): 1.8V to 5.5V for internal circuitry.
Switch Resistor (External Component): Set switch frequency of the internal
power MOSFET by connecting an external resistor to VDD. Connecting the
external resistor to GND disables the switch oscillator and shuts down the
device.
EL Resistor (External Component): Set EL frequency of the internal H-bridge
driver by connecting an external resistor to VDD. Connecting the external
resistor to GND disables the EL oscillator.
Ground
Switch Node (Input): Internal high-voltage power MOSFET drain.
Regulated Boost Output (External Component): Connect to the output capacitor
of the boost regulator and connect to the cathode of the diode.
EL Output: Connect to one end of the EL lamp. Polarity is not important.
EL Output: Connect to one end of the EL lamp. Polarity is not important.
