Example Circuit
This application example uses the SC620 to drive 3
backlight LEDs, plus a voice coil actuator for lens auto-focus
and one open-drain digital output. Independent outputs
allow these functions to be supported simultaneously.
The VIN supply is typically single cell Li-Ion or 5.0V. VIN
and the LED anode voltage may be supplied by different
sources. The operating voltage limit of [VIN - 1.5V] at
the sink pins must be observed to achieve the speci
fi
ed
accuracy of the device.
