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 microprocessorвЂ™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 applicationsвЂ”
anywhere a conventional bulb might
be found. Some new white LEDs,
such as LumiledsвЂ™ Luxeonв„ў 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 …
