ICN205316-Channel PWM Constant Current LED Sink Driver
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%.
ICN2038S16-Channel Constant Current LED Sink Driver with Dual Latch
The ICND2038S 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 ICND2038S exploits current precision controlling technology，which makes error between ICs less than ±2.0%, and error between channels less than ±2.0%. At ICND2038S 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.
ICND2038S contains two 16-bit shift registers and latches which convert serial input data into parallel output format. For integrated dual latches, ICND2038S could get higher refresh rate.
