The AL1783 from Diodes Incorporated is a Three-Channel Linear LED Driver IC that has been designed to target connected, commercial, industrial, and RGB LED lighting applications.  It requires an input voltage of 6.5 - 60 V. This AEC-Q100 qualified LED driver IC includes circuits for current reference, dimming signal processing, PWM control, oscillator, pre-regulator, and current ratio. It provides independent PWM dimming and current-setting controls for each channel. This LED driver IC’s key merits are attributed to a compact solution, eBOM cost effectiveness, excellent PWM dimming performance, low standby power, ease of system implementation, and up to 60V input and LED pin operating voltage.

The AL1783 consists of built-in under voltage lockout (UVLO), over-voltage protection, LED string open/short protection (LED short/open), and over-temperature protection (OTP) circuits to prevent false triggers or over-heating-related damages. This RoHS-compliant LED driver IC is available in a surface-mount package that measures 4.90 x 6.80 mm and is ideal for RGB lighting, horticulture lighting, architecture lighting, industrial lighting, commercial lighting, i.e., ceiling and panel lighting, and connected lighting applications.
