V. EL Lamp Brightness Regulation
Regulating the DC supply input voltage to the D381A will result in a constant brightness level from the EL lamp,
regardless of battery voltage. In this example, a Micrel voltage regulator is used.

VI. Output Voltage Limit Control
An EL driver system using the D381A driver IC should be designed such that the output voltage does not exceed the
maximum rated value of 220Vpp. A pair of zener diodes connected to the output as shown below is recommended to
limit Vout to within 200Vpp or less. This circuit protects the device from over-voltage when typical performance is near
the maximum limit for the D381A.
