II. Driving Multi-segment Lamps
The D365 may be used to drive multiple EL lamp segments. An external transistor switching circuit is used to turn each
lamp segment on or off independently or simultaneously. A high signal at the corresponding E input will enable the
corresponding lamp segment. In this configuration, EL Lamp 1 is always turned on when the IC is enabled. Otherwise,
always make sure that at least one lamp segment is selected to be on when the D365 is enabled.

III. Lamp Frequency Control with an External Clock Signal
An external clock signal may be used to control the inductor oscillating frequency (HF) and, consequently, the EL lamp
frequency (LF) of the D365. HF and LF can be varied to synchronize the EL driver with other elements in the
application. An internal divider network in the IC creates a ratio of HF/LF=72.
