ICN2037

16-Channel Constant Current LED Sink Driver with Dual Latch

Description

The ICN2037 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 ICN2037 exploits current precision controlling technology,which makes error between ICs less than ±2.5%, and error between channels less than ±3.0%. At ICN2037 output stage16-regulated output ports are designed to provide uniform and constant current sinks for driving LEDs within a large range of forward voltage(VF) variations.

ICN2037 contains two 16-bit shift registers and latches which convert serial input data into parallel output format. For integrated dual latch, ICN2037 could get higher refresh rate.
