60V THREE INDEPENDENT PWM CHANNEL LINEAR LED DRIVER

Description

Pin Assignments

The AL1783 is a three-channel linear LED driver with independent

PWM dimming and current-setting controls for each channel. The

device is designed to target connected, commercial, industrial, and

RGB LED lighting applications.

The key merits of the AL1783 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.
