2014 10 13 TM1808 LED IC PWM 16 . 12 PWM . 12 LED 24V 5V. 3 Description. Grayscale (GS) Control With Enhanced Spectrum. The TLC5971 device is a 12-channel, constant-. PWM: current sink driver. Each output channel has. 16-Bit (65536 Steps) individually adjustable currents with 65536 PWM. Global Brightness Control (BC): grayscale (GS) steps. Also, each color group can be. The CAT4101 is a constant current sink driving a string of high brightness LEDs up to 1 A with very low dropout of 0.5 V at full load. It requires no inductor, provides a low noise operation and minimizes the number of components. The LED current is set by an external resistor connected to the RSET pin. The LED pin is.
