Each features True Color PWM dimming with 3,000:1 ratio or analog dimming with 10:1 ratio. Their compact, robust, and complete solution permit a quick design-to-fabrication of LED string driver circuits in applications such as industrial illumination, backlight displays, scanners, and automotive as well as avionics lighting.
The LTM8042 and LTM8042-1 are switching regulator LED drivers with very accurate output current line regulation, ideal for driving LEDs or for general purpose current sourcing. Inductors, capacitors, regulator IC and compensation circuitry are enclosed and protected in a plastic package resembling an IC.
