AL1793AFE-13 LED Driver IC 3 Output Linear Analog PWM Dimming 500mA U-DFN4030-14

AL1793AFE-13 LED Driver IC 3 Output Linear Analog PWM Dimming 500mA U-DFN4030-14

Description

The AL1791/1792/1793/1794 (or collectively AL179x), a single/multichannel LED driver with analog and PWM dimming control, is targeted for Tunable White/Color Smart Lighting application. It serves as the LED driving element along with AC-DC Power Conversion Block and Intelligent wireless MCU as an emerging smart-connected lighting system configuration. The key merits attribute to costeffectiveness, dimming performance, low standby power, ease of system implementation, and great scalability. AL1791, AL1792, AL1793, and AL1794 are 1-channel, 2-channel, 3-channel, and 4- channel LED drivers, respectively. The IC is available in U-DFN-4030-14 package.
