LP5817 3-Channel RGB LED Driver

Texas Instruments LP5817 3-Channel RGB LED Driver has an ultra-low operation current of 0.1µA (typ.) in shutdown mode, 0.15mA (typ.) when enabling the device, and 0.2mA (typ.) when illuminating LEDs. The Texas Instruments LP5817 uses analog and PWM dimming methods to achieve powerful performance. The output current of each LED can be adjusted in 256 steps from 0.1mA to 25.5mA or 0.2mA to 51mA. The 8-bit PWM generator enables audible-noise-free and smooth dimming control for LED brightness.

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.
