III. Two-Level Dimming
Toggle switching between two different EL lamp brightness levels may be achieved with the following circuit. When
DIM is low, the external pnp transistor is saturated and the EL lamp runs at full brightness. When DIM is high, the
external pnp turns off and the 47
resistor reduces the voltage at (V+) and dims the EL lamp.

IV. Lamp Frequency Control with an External Clock Signal
An external clock signal with a 50% duty cycle may be used to control the EL lamp frequency (LF). This technique
allows the designer flexibility to synchronize the El driver IC with other elements in the application. The output lamp
frequency will be the same frequency as the input clock signal. For example, if a 250Hz input clock signal is used, the
resulting lamp frequency will be 250Hz. The clock signal voltage should not exceed V+.
