A broad range of constant current driver IC can be searched. Starting at low power, single channel LED driver for display backlight or battery applications over multi-channel LED driver for large screen consumer applications all the way to high-power and high-brightness LED driver for flashlight, interior lighting or industrial applications. Also products with special qualifications for automotive like AEC-Q100 can be searched. For voltage regulation and power management supply please use the DC/DC Converter IC with internal MOSFET product Selector or for high power the DC/DC Controller IC with external MOSFET product Selector.
