Description
The ICND2047 is a 16-channel constant current sink 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 ICND2047 exploits current precision controlling technology，which makes error between ICs less than ±2.0%, and error between channels less than ± 2.0%. At ICND2047 output stage ， 16-regulated output ports are designed to provide uniform and constant current sinks for driving LEDs within a large range of forward voltage(VF) variations.
ICND2047 contains two 16-bit shift registers and latches which convert serial input data into parallel output format. For integrated dual latches, ICND2047 could get higher refresh rate. ICND2047 used DDR structure to increase the number of cascades.
