PIN ASSIGNMENTS
Pin 1 — EL1/EL2 — Electroluminescent Lamp
Output Select. Selects either EL1 Output
when input is LOW or EL2 Output when
input is HIGH.
Pin 2 — V
— Positive Battery Power Supply.
This pin should be bypassed with a 0.1
μ
F
capacitor.
Pin 3 — R
— Oscillator Resistor. Connecting
a resistor between this pin and V
sets the
frequency of the internal oscillator.
Pin 4 — ON/OFF — Enable. When driven
HIGH, this input pin enables the internal
oscillator and EL driver outputs.
Pin 5 — V
— Power Supply Ground. Connect
to the lowest circuit potential, typically
ground.
Pin 6 — COIL — Coil. The inductor for the
boost converter is connected from V
BATT
to
this pin.
Pin 7 — CAP — Integrating Capacitor. An
integrating capacitor connected from this pin
to ground filters out any coil switching spikes
or ripple present in the output waveform to
the EL lamps. Connecting a fast recovery
diode from COIL to CAP increases the light
output of the EL lamp.
Pin 8 — EL COMMON — Electroluminescent
Lamp Common. This is a high voltage lamp
driver output pin common to both EL lamps.
Pin 9 — EL2 — Electroluminescent Lamp Out-
put 2. This is a high voltage lamp driver
output pin connect to the second EL lamp.
Pin 10 — EL1 — Electroluminescent Lamp
Output 1. This is a high voltage lamp driver
output pin to connect to the first EL lamp.
