16-CHANNEL CONSTANT CURRENT
LED DRIVER WITH PWM
FEATURES
* 16-channel constant output, each has 4096 grayscale control (12 bit PWM)
* Output constant current: 2 - 90mA
* Current accuracy (All output ON)
Between BITS <±3%
Between IC’s <±6%
Output Current 4~50mA
* Output current adjustable through an external resistor, and current gain is controlled through program (6 bit)
* Serial data in/out
* Interleave time delay of output channel
* Fast response for output port (tr/td=50ns)
* 25MHz clock frequency
DESCRIPTION
PA5030 is a 16-channel constant current LED driver with built-in 12-bit PWM , each channel has an individually
adjustable 4096 step grayscale pulse width modulation brightness control. The constant current reference of 16
channels can be set through external resistor R-EXT, and the current gain A can be set through software, the actual
input current Iout is Iset X A.
Grayscale PWM and current gain A are moved to chip through
SDI at rising edge of DCLK, and output through SDO after 12 clocks.
The ON/OFF of the output port is controlled through the combination of DCLK and LATCH timing and logic,
and reset the PWM counter.
