Additional Details

The LTM8042 is a complete μModule^® (power module) Boost LED Driver specifically designed to drive LEDs up to 1A, while the LTM8042-1 drives up to 350mA. It combines a boost power topology with a unique current loop to operate as a constant-current source. The PWM input provides as much as 3000:1 LED dimming, while 10:1 analog dimming can be accomplished by a single resistor or analog voltage applied to the CTL pin. As with any boost topology, the LTM8042/LTM8042-1 has an uninterrupted current path between its input and output and is thus intolerant to a short-circuit or overload from the output to ground.


# WHITE LEDS	LED CURRENT	12V_IN	24V_IN
6	1A	LTM8042
7	350mA	LTM8042-1
8	1A		LTM8042
9	350mA		LTM8042-1

The LTM8042/LTM8042-1 is packaged in a thermally enhanced, compact overmolded land grid array (LGA) package. The LTM8042/LTM8042-1 is Pb-free and a RoHS compliant.
