  42V High Power Density Buck Regulators in a Tiny QFN
  Package
  Design Note 1038
  Ying Cheng
  Introduction
  Power dissipation is a significant problem facing the
  designers of DC/DC converters in industrial and automotive applications, where high currents are required,
  but space is limited. It is possible to produce a highly
  efficient regulator from high performance discrete
  components, but expense and solution footprint make
  this approach prohibitive. The LT8612/LT8613 high
  efficiency buck regulators integrate all the necessary
  components into a single IC, significantly reducing
  the DC/DC converter size, even when faced with high
  step-down ratios. These devices can also be paralleled
  to increase the output current capability and spread
  the load and heat. high efficiency power switches allows these switches,
  the boost diode, internal compensation and all necessary circuitry to be encapsulated in a tiny 3mm Г— 6mm
  QFN package without overheating. Figure 1 shows a
  typical 5V/30W LT8612 converter; its efficiency and
  power loss are demonstrated in Figure 2. Even with
  an input voltage of 24V, the LT8612 can produce a
  30W output with no more than 50В°C temperature rise. …

  Other desirable features included in these
  regulators are ultralow quiescent current
  to maximize battery life, and high switching frequency to minimize solution size
  and avoid noise-sensitive frequency bands. Figure 2. Even with an input voltage
  of 24V, the LT8612 can produce a 30W
  output with no more than 50В°C temperature rise. At the other end of the load
  spectrum, the LT8612/LT8613 uses low
  ripple Burst ModeВ® operation to enhance
  efficiency in ultralow load situations. HIGHLY EFFICIENT 42V, 6A
  REGULATORS IN
  3mm Г— 6mm PACKAGE The minimum on-times of LT8612/
  LT8613 are as low as 40ns, allowing
  for high VIN/VOUT ratios even at high …

  High Performance Portable DC Bench Power Supply: Save Money and Free Up Bench Real Estate by Building Your Own &mdash LT Journal

  High Performance Portable DC Bench Power Supply:
  Save Money and Free Up Bench Real Estate by
  Building Your Own
  Keith Szolusha The bench power supply, along with the soldering iron and
  handheld multimeter, is a required item in any electronics
  lab toolbox. Some projects require only a single, constant
  voltage supply, but more often, properly testing and
  debugging a project demands a variety of voltages and
  currents. Significant debugging time can be saved by
  using a high performance adjustable bench supply to
  dial in voltage and current at will. Unfortunately, typical
  universal adjustable bench power supplies are bulky and
  expensive—at least the better-performing versions—and
  have a number of limitations. None are truly portable
  (handheld) due to necessary heat dissipation structures.
  Furthermore, even high cost supplies do not support zero
  current or voltage, and cannot match the transient and
  short performance exhibited by the supply shown here.
