  DESIGN IDEAS 4A, 4MHz Monolithic Synchronous
  Regulator with Tracking offers a
  Compact Solution for Power
  Supply Sequencing
  by Joey M. Esteves
  Introduction
  The LTC3416 offers a compact and
  efficient voltage regulator solution for
  systems that require power supply
  sequencing between different supply
  voltages. Many microprocessors and
  DSP chips need a core power supply
  and an I/O power supply that must
  be sequenced during start-up. Without proper power supply sequencing,
  latch-up or excessive current draw
  may occur that could lead to damage
  to the microprocessor’s I/O ports or
  the I/O ports of a supporting device
  such as memory, logic, FPGAs, or
  data converters. The LTC3416 operates from an input voltage range of
  2.25V to 5.5V and can generate an
  output voltage between 0.8V to 5V.
  The internal power MOSFET switches …

  DESIGN IDEAS Boost Converter Drives 1A White LEDs
  by Keith Szolusha
  White LEDs are brighter and more
  powerful than ever. High-power white
  LEDs, because of their extreme luminous density and ultra-compact size,
  are replacing conventional bulbs in
  flashlights, headlamps, streetlights,
  and many automotive applications—
  anywhere a conventional bulb might
  be found. Some new white LEDs,
  such as Lumileds’ Luxeon™ series,
  improve on conventional bulbs in several characteristics, including greater
  luminescence, improved response
  time, and increased durability with
  decreased size and cost.
  The challenge in using white LEDs
  in portable applications is powering
  them with the wide input voltage range
  that batteries present, such as 3.3V to
  4.2V from a lithium-ion. LEDs require
  constant current to maintain constant
  luminosity. The battery-LED DC/DC
  converter must both step up and step …
