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.

PCA9955 16-channel Constant Current LED Driver

NXP Semiconductor PCA9955 LED Drivers are I²C controlled 16-channel constant current drivers designed for dimming and blinking 57mA Red/Green/Blue/Amber (RGBA) LEDs in amusement products. Each channel has an 8-bit resolution (256 steps) 31.25kHz PWM controller with a duty cycle that is adjustable between 0% to 99.6%. This feature allows each LED to be set to a specific brightness. An additional 8-bit resolution (256 steps) group PWM controller has both a fixed frequency and an adjustable frequency. This additional controller is used to either dim or blink all the LEDs with the same value.
