Applications Information (continued)

Application Circuit Examples

Main Backlight Plus Sub-panel Backlight Plus Single

RGB LED

This example uses the SC620 to drive a main display, a

sub-panel display, and an RGB LED. Independent outputs

allow these functions to be supported simultaniously at

different intensities. The V

supply is typically single cell

Li-Ion or 5.0V. V

supply and LED anode voltage may

be from different sources. The operating voltage limit of

— 1.5V) at the sink pins must be observed to achieve

the specified accuracy of the device.
