Example Circuit

This application example uses the SC620 to drive a

main display, a sub-panel display and an RGB LED.

Independent outputs allow these functions to

supported simultaniously at different intensities. The VIN

supply is typically single cell Li-Ion or 5.0V. VIN supply

and LED anode voltage may be from different sources.

The operating voltage limit of [VIN - 1.5V] at the sink pins

must be observed to achieve the speciﬁed accuracy of the

device.
