LTM8042 Datasheet (Linear Technology) - uModule Boost LED Driver and Current Source

LTM8042, uModule Boost LED Driver and Current Source

The LTM®8042 is a complete µModule® 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, whil
