8 Channel Constant Current Led Sink Drivers

Low output voltage operation on the led channels as low as 0 4 v for 2 to 100 ma led current allows for more power efficient designs.

8 channel constant current led sink drivers.

Since each output current adjusted through single external output is independently controlled they can be. How to select a rgb led driver. Since each output is independently controlled they can be programmed to be on or off by the user. Led channel currents are programmed together via an external rset resistor.

Power management guide 2018 rev. The tlc591x constant current led sink drivers are designed to work alone or cascaded. Led drivers are the driving force that provides and regulates the necessary power to make sure the leds operate in a safe and consistent manner. The high led voltage vled allows for the use of a single led per output or multiple leds on a single string.

Tlc59116 16 channel fm i2c bus constant current led sink driver datasheet rev. Since each output is independently controlled they can be programmed to be on or off by the user. Stap08dp05 low voltage 8 bit constant current led sink driver with output error detection for automotive applications stmicroelectronics the stap08dp05 is a monolithic low voltage low current power 8 bit shift register designed for led panel displays. The cat4008 is an 8 channel constant current driver for led billboard and other general display applications.

Drive leds in virtual reality applications. Led channel currents are programmed together via an external rset resistor. The device features two operating modes bus driven or standalone and independent 7 bit pwm dimming with exponential brightness correction on each channel making it suitable for rear combination lights and interior lighting systems where high. The high led voltage vled allows for the use of a single led per output or multiple leds on a single string.

The tlc591x constant current led sink drivers are designed to work alone or cascaded. Led driver description the cat4008 is an 8 channel constant current driver for led billboard and other general display applications. Power management guide 2018 rev. The aled1262zt is a 12 channel 60 ma led driver tailored to meet requirements for rear combination light applications with graphic animation.

Constant current and constant voltage drivers are both viable options for a power supply for led light sources what differs is the way in which they deliver the power. Low output voltage operation on the led channels as low as 0 4 v for 2 to 100 ma led current allows for more power efficient designs.
