LвЂ‰DESIGN FEATURES В±32V Triple-Output Supply for LCDs,
CCDs and LEDs Includes Fault
Protection in a 3mm Г— 3mm QFN
by Eko T. Lisuwandi Introduction
The task of designing a battery powered system with multiple high voltage
supplies is a daunting one. In such
systems board space is at a premium
and high efficiency is required to
extend battery life. Supplies must be
sequenced in start-up and shut-down,
and multiple supplies must be able to
maintain regulation without interaction across supplies.
The LT3587 is a 1-chip solution
that combines three switching regulators and three internal high voltage
switches to produce two high voltage
boost converters and a single high voltage inverter. The LT3587 is designed to
run from inputs ranging from 2.5V to
6V, making it ideal for battery powered
systems. Small package size and low component count produces a small,
efficient solution. Typical applications
include digital still and video cameras,
high performance portable scanners
and display systems, PDAs, cellular …

LвЂ‰DESIGN IDEAS Complete Power Solution for Digital
Cameras and Other Complex
Compact Portable Applications
by Brian Shaffer Introduction
Digital cameras, portable GPS systems,
MP3 players and other feature-rich
mobile devices have complicated
power requirements. In these complex
devices, the flow of power must be
carefully managed between a number of specialized sources and loads,
including charging/discharging the
battery, current-limited USB power
and a set of multivoltage power supply rails, including negative rails for
CCDs or LCDs. The supply rails must
be sequenced and tracked and faults
must be handled cleanly and communicated to a microcontroller.
When these requirements are
added together, the task of squeezing
an efficient and robust power system
into a handheld device can seem near
impossible. Linear Technology solves
this problem with a family of devices
called PMICs (Power Management Integrated Circuits) that greatly simplify …
