CS8903 is a 3-channel PWM enabled LED driver IC, which is designed for LED lighting or display applications.
At CS8903 output channel, 3-channel constant current value set is adjustable with 3 corresponding external resistors and the internal PWM control circuitry to match RGB color characteristics.
CS8903 built in a voltage regulator, which provides supply voltage range from 6.0V to 24V, and built in an oscillatorfor PWM functioning. Data (DAO) and clock (CKO) buffer outputs are designed for cascading another chip.
In addition, CS8903 guarantees to stand maximum 24V at the output channel.
