LTM8042IV-1#PBF

LED照明驱动器 350mA Boost LED Drive uModule

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