LED照明驱动器 16 Channel Constant Crnt LED Drvr
DESCRIPON
The TLC59283 is a 16-channel, constant-current sink light-emitting diode LED driver. Each channel can
be individually controlled with a simple serial communications protocol that is compatible with 3.3-V or 5-V CMOS logic levels, depending on the operating VCC.
