• Manufacturer Part Number: ncp5623b
• Description: Triple Output I2c Controlled Rgb Led Driver
• Manufacturer: ON Semiconductor

ANALOG SECTION:
6. The overall output current tolerance depends upon the accuracy of the external resistor. Using 1% or better resistor is recommended.
7. The external circuit must not force the I
8. This parameter, derived from the 1 MHz clock, is guaranteed by design, not tested in production.
DIGITAL PARAMETERS SECTION:
NOTE:
9. Test guaranteed by design and fully characterized, not implemented in production.
