Description
The ICN2053 is a 16-channel PWM constant current sink LED driver for 1:32 time multiplexing applications. The constant-current value of all 16 channels is set by a single external resistor.
ICN2053 converts serial input date into the gray scale of each pixel by a 16-bit shift register. ICN2053 detects individual LED open errors without extra components. ICN2053 also integrated pre-charge circuit for ghosting reduction.
The ICN2053 exploits precise current regulation technology, with both channel-to-channel error and chip-to-chip error less than ±2.0%.
