2. In case of driving both Backlighting (Main/Sub Displays) and Key pad Illumination
By using external MOS FET, the system of driving for main , sub display and Key pad Illumination is also composed.
3. LCD Backlight system (Only Main Display)
In case sub display is not connected, Vout 2 is terminated when CE2 terminal fix to the ground, then only Vout 1 can be
operated. In case of this application, Vout2 and FB2 should be open connection.
In case of using this device with 190mA of total output current, as shown application figure 5, Vout 1 and Vout 2 are connected
as common output. In this case, CE1 and CE2 are applied with common signal, and FB2 should be open connection.
