Chipone ICND2037S Constant Current LED Driver


Category: Brand:


The ICND2037S 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 ICND2037S exploits current precision controlling technology,which makes error between ICs less than ±3.5%, and error between channels less than ±3.0%. At ICND2037S 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.

ICND2037S contains two 16-bit shift registers and latches which convert serial input data into parallel output format. For integrated dual latches, ICND2037S could get higher refresh rate.
