  ВµModule LED Driver Integrates All Circuitry, Including the
  Inductor, in a Surface Mount Package – Design Note 445
  David Ng
  Introduction
  Once relegated to the hinterlands of low cost indicator
  lights, the LED is again in the spotlight of the lighting
  world. LED lighting is now ubiquitous, from car headlights
  to USB-powered lava lamps. Car headlights exemplify
  applications that capitalize on the LED’s clear advantages—unwavering high quality light output, tough-assteel robustness, inherent high efficiency—while a USB
  lava lamp exemplifies applications where only LEDs work.
  Despite these clear advantages, their requirement for
  regulated voltage and current make LED driver circuits
  more complex than the venerable light bulb, but some new
  devices are closing the gap. For instance, the LTM В®8040
  ОјModuleв„ў LED driver integrates all the driver circuitry
  into a single package, allowing designers to refocus their
  time and effort on the details of lighting design critical
  to a product’s success.
  A Superior LED Driver
  The LTM8040 is a complete step-down DC/DC switching converter system that can drive up to 1A through a
  string of LEDs. Its 4V to 36V input voltage range makes
  it suitable for a wide range of power sources, including
  2-cell lithium-ion battery packs, rectiп¬Ѓed 12VAC and …
