Chipone ICND2150S PWM LED Driver


Category: Brand:


The ICND2150S is a 16-channel PWM constant current sink LED driver for 1:16 time multiplexing applications. The constant-current value of all 16 channels is set by a single external resistor.

ICND2150S converts serial input date into the gray scale of each pixel by a 16-bit shift register. ICND2150S detects individual LED open errors without extra components. ICND2150S also integrated pre-charge circuit for ghosting reduction.

The ICND2150S exploits precise current regulation technology, with both channel-to-channel error and chip-to-chip error less than +/- 2.0%.
