requirements, the following charts will suggest the TK6592x family of EL Drivers which have higher drive capabilities. To
utilize the following charts in selecting an appropriate coil, perform the following steps:
1)
From the following charts, select the chart that matches the part number of the Toko EL Driver that will be used in
the application. The part number of the Toko EL Driver will be dependant upon the desired frequency of the EL panel
(e.g., TK65911 = 200Hz).
Determine input supply voltage range (e.g., 4 to 6 V). The x-axis of the following charts represent the minimum
expected supply voltage. Below this minimum supply voltage the EL Driver output may begin to droop. On the
appropriate chart, draw a vertical line upward from the minimum supply voltage represented on the x-axis (e.g., 4V).
Draw a horizontal line passing through the chosen inductor value on the y-axis (e.g., 820
μ
H).
The vertical and horizontal lines drawn in steps 2 and 3 respectively will intersect at a point. This point will lie in one
of four regions of the chart (e.g., D31FU). These four regions suggest which family of Toko Coils to use.
2)
3)
4)
Of the three coil families suggested in these charts, the D31FU has the smallest physical size but also has higher DC
resistance. The D52FU series of coils has the largest physical size and the lowest DC resistance. The D52FU or the
D32FU can be used as a reasonable substitute for the D31FU. Similarly, the D52FU can be used as a replacement for
the D32FU. Substituting a coil with lower DC resistance will generally result in a system that will consume less power
supply current.
