double side FR-4 board.)

Note 6. When calculating thermal design, please include the heat generated by the internal regulator along

with the LED pins.

• The case of fixed current output:

IC power consumption

= LED pins power consumption (LED current*LED pin voltage) * LED numbers

+Internal LDO power consumption [(VIN-VDC1) * (VDC1 output current+IC consumption (8.5mA))]

+VDC1*IC consumption (8.5mA)

• The case of open drain output:

IC power consumption

= LED pins power consumption (LED current*LED current*LED ON-resistor 9.3ohm)*LED numbers

+Internal LDO power consumption [(VIN-VDC1) * (VDC1 output current+IC consumption (2mA))]

+VDC1*IC consumption (2mA)

Note 7. The maximum value is limited to 5.5V when the VDC1 exceeds 5.2V.

WARING: Operation at or beyond these limits may result in permanent damage to the device.

Normal operation is not guaranteed at these extremes.
