具有 3.3V 线性稳压器的 12 通道 16 位 ES-PWM RGB LED 驱动器
The device is a 12-channel, constant-current sink driver. Each output channel has individually adjustable currents with 65536 PWM grayscale GS steps. Also, each color group can be controlled by 128 constant-current sink steps with the global brightness control BC function. GS control and BC are accessible through a two-wire signal interface. The maximum current value for each channel is set by a single external resistor. All constant-current outputs are turned off when the IC is in an overtemperature condition.
