Description
Input Supply Voltage: 1.8V to 3.5V
External Switch Resistor: Set switch frequency of the internal power MOSFET by connecting an
external resistor to V_DD. Connecting the external resistor to GND disables the switch oscillator and
shuts down the device.
External EL Resistor: Set EL frequency of the internal H-bridge driver by connecting an external
resistor to V_DD. Connecting the external resistor to GND disables the EL oscillator.
Ground Return
Internal Switch Node: Internal high-voltage power MOSFET drain
Regulated Boost Output: Connect to the output of external storage capacitor of the boost regulator
and connect to the cathode of the diode
EL Output: Connect to EL lamp - Polarity does not matter
EL Output: Connect to EL lamp - Polarity does not matter
