TK6593x
DESIGN CONSIDERATIONS
INDUCTOR VALUE SELECTION
Designing an EL Driver utilizing the TK6593x is a very simple task. The primary component affecting the behavior of the
converter is the inductor. Essentially, the entire design task primarily consists of selecting the proper inductor value and
type given the operating conditions of the EL Panel (e.g., lamp capacitance, frequency, output voltage, supply range).
The following tables and charts are intended to simplify the selection of the inductor.
Given the capacitance of the EL Lamp, and the peak output voltage requirements, the following table can be utilized to
select the value of the inductive component.
TABLE 4: PEAK OUTPUT VOLTAGE VS. INDUCTOR VALUE AND LAMP CAPACITANCE
As an example as to how the above table is to be used, assume that we have a 4-square-inch panel (30 nF capacitance)
and we would like the peak-to-peak voltage across the lamp to be 140 V. The peak voltage on either terminal would be
70 V (140 V / 2). Referring to the table above, we can see that using a 470
μ
H coil the peak voltage developed across
a 30 nF Lamp would be approximately 69 V. In this particular example, the inductive component should have a value of
470
μ
H.
INDUCTOR TYPE SELECTION
After the value of the inductor has been selected, an appropriate coil type needs to be selected taking into account such
factors as DC resistance and current capability. The following charts can be utilized for selecting the proper family of Toko
Coils. Furthermore, the following charts will also indicate if the TK6593x is the appropriate driver given the frequency and
input supply requirements. The following charts will indicate whether or not the TK6593x has sufficient drive capability,
