| Dear Sir/Madam
Electrical
power is necessary especially in the automation industry – one
of the big electronic markets in Europe. This is shown at the
SPS/IPC Drives exhibition in Nuremberg were the automation industry
meets every year to discus future trends and present actual
products. This newsletter features some of them. Enjoy!

Power-Management
MOSFETs (NEC Electronics)
The
TO-263-7 PowerMOSFET is part of the NP series of low-voltage
power-management devices. It features advanced packaging solutions
to reduce leakage current and manage heat dissipation more efficiently.
The devices offer on-state resistances Rds(on) of
1.5 mOhm maximum for a VDSS of 40V and a VGS of 10V, and are
well-suited for applications such as automotive, low-voltage
DC motor control and uninterruptible power supplies.

N-Channel
MOSFET (Fairchild)
The
FDS881XNZ series of high-efficiency N-channel MOSFETs supports
up to 8kV ESD (HBM) voltage protection, a figure 90% higher
than that of existing devices on the market, claims manufacturer
Fairchild Semiconductor.

Full-Brick
DC/DC Converter (Ericsson Power Modules)
The
PKY4716PI DC/DC converter platform delivers 700W of output power
and typically exceeds 94% of efficiency in the industry-standard
full-brick format and footprint. Aimed at the telecoms market,
the device exhibits an efficiency curve that is virtually flat
from 30 to 100% load. It handles both 48 and 60V system voltages
and has an input-voltage range of 36 to 75V (though it can withstand
up to 100V input continuously).

1.2A
LED Driver (Texas Instruments)
The
TPS61050 LED-driver IC is based on a high-frequency synchronous-boost
topology with a constant-current sink to drive single, high-brightness
white-light emitters. The tiny 2x1.5x0.625mm device uses an
inductive fixed-frequency pulse-width-modulation-control-scheme
utilising small external components, and minimising input-ripple
current for applications, such as a white LED flash for camera
phones, smart phones and PDAs, or other general lighting systems.

SnakeBytes
and Venom in High Performance Analogue
This
article by Alan Hutton from National Semiconductor looks at
the key features of the reference platform SnakeBytes and focuses
on how the high performance analogue content from National can
aid system designers with their board level partitioning across
the digital and analogue divides.

Helping
With Water Provision
This
article by John Crockett from Digi International details
the implementation of a wireless network based on low-power
stand-alone radio modems to remotely monitor water levels in
the mountainous region of Monterrey and ensure efficient water
treatment and supply.

Single
op amp achieves doublehysteresis-transfer characteristic
In
process-control applications requiring discontinuous controllers,
the most elementary choice is a two-position-mode or on/off
controller. This Design Idea by Herminio Martínez, Encarna García,
and Juan Gámiz from the Technical University of Catalonia in
Barcelona, Spain, shows one simple way to implement a three-position
controller with just one op-amp.

Inverting
sample-and-hold amplifier requires no external resistors
Many
applications require a sampling circuit whose output is inverted
with regard to the respective sample of an input signal. A simple
approach is a cascade of a common non-inverting sample-and-hold
amplifier and an inverting amplifier. The inverting sample-and-hold
circuit in the Design Idea by Marián Štofka from the Slovak
University of Technology in Bratislava, Slovakia, uses the Analog
Devices’ AD8592 dual op amps, which have a high-quality shutdown
function and uses no external resistors.

Europe
Leading the Way in Digital Terrestrial TV
Europe
is leading the world in the fast-growing digital terrestrial
platform (DTT), though other regions are gaining momentum, reports
In-Stat. With analogue shutoffs (ASOs) approaching in North
America and Western Europe, strong drivers for digital terrestrial
set top boxes are on the horizon as consumers transition from
analogue to digital. While other regions are further behind
the digital curve, actions are being taken to expand digital
services; whether it is formally adopting a standard (e.g. Honduras
and ATSC) or anticipating DTT launches (e.g. Brazil), digital
is becoming a global change.

Electromagnetic
Compatibility in Power Systems, by Francesco Lattarulo (Editor)
In
addition to textbooks providing a thorough background on basic
EMC aspects, thus being well-tailored for students and those
which want to get in contact with this discipline. The most
can be made to jointly sustain a helpful and practicable publishing
activity is to supply specialised monographs or miscellanies
of selected topics. This is the object of the present book which
tries to rather discuss special subjects, or throw out suggestions
for reformulating conventional approaches, than to appear as
a reference text.
