AL1783
AL1783 is 60V THREE INDEPENDENT PWM CHANNEL LINEAR LED DRIVER manufactured by Diodes Incorporated.
Description
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, mercial, industrial, and RGB LED lighting applications.
The key merits of the AL1783 are attributed to a pact solution, e BOM 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 is available in the TSSOP-16EP (Type DX) package to minimize PCB space and external ponent count.
