16-Channel PWM Constant Current LED Sink Driver
The ICND2055 is a 16-channel PWM constant current sink LED driver for 1:32 time multiplexing applications (with 16 KB SRAM). The constant-current value of all 16 channels is set by a single external resistor.
ICND2055 converts serial input date into the gray scale of each pixel by a 16-bit shift register.ICND2055 detects individual LED open errors without extra components. ICND2055 also integrated pre-charge circuit for ghosting reduction.
The ICND2055 exploits precise current regulation technology, with both channel-to-channel error and chip-to-chip error less than ±2.0%.
