IS31FL3749 Matrix LED Driver

Lumissil IS31FL3749 Matrix Light Emitting Diode (LED) Driver is a 24x4 local dimming LED driver with 24 high voltage (16V) constant current channels. Each LED can be controlled by an 8-bit output control register, which allows fine-tuning of the current for RGB colour mixing. The IS31FL3749 LED driver supports 8-bit, 16-bit, 8+4-bit dithering and 8+8-bit dithering Pulse Width Modulation (PWM) modes. This LED driver can be turned off with minimum current consumption by pulling the SDB pin low or using the software shutdown functionality. The IS31FL3749 LED driver features a 60mA maximum output current for each channel, which can be adjusted by three 8-bit global control registers group.

IS32LT3175N/P Single-Channel Linear LED Drivers

ISSI IS32LT3175N/P Single-Channel Linear LED Drivers come with fade in/out and PWM dimming. The regulators serve as a stand-alone LED driver-configurable from 20mA to 150mA with external resistors, no microcontroller is necessary. A logic level “courtesy light” signal from the PWM pin can be interfaced to precisely drive the LED channel. The IS32LT3175P obtains a positive polarity PWM signal. In addition, the IS32LT3175N obtains a negative polarity PWM signal. The regulator integrates a 63-step fade-in and fades out the algorithm (Gamma correction). This causes the output LED current to increasingly rise up to the full source value after the EN pin is pulsed.
