Chipone ICN2049 / ICND2049 Constant Current LED Driver
The ICND2049 is a 16-channel constant current output LED driver. All 16-channels constant current can be set by a single external resistor, which provides users flexibility in controlling the light intensity of LEDs.
The ICND2049 exploits current precision controlling technology, which makes error between ICs less than ±2.0%, and error between channels less than ± 2.0%. At ICND2049 output stage, 16-regulated output ports are designed to provide uniform and constant current for driving LEDs within a large range of forward voltage(VF) variations.
ICND2049 contains two 16-bit shift registers and latches which convert serial input data into parallel output format. For integrated dual latches, ICND2049 could get higher refresh rate.
