The ULWP2R range of fusible wirewound resistors
enables designers to build compact and affordable
fire prevention into their products. TT Electronics also
offers other 2W rated wirewound and metal film power
resistors that are now available in radial taped format
including the wirewound high surge WHS series.

Industry’s smallest regulated and isolated
9 W DC-DC converters offer 4:1 input range
XP Power announced the ITZ series of compact
regulated 9 Watt DC-DC converters. Believed to be the
industry’s smallest 9 W DC-DC converters, the units
accommodate an ultra-wide 4:1 input and are available
with single and dual outputs. Packaged in an ultra-
compact metal cased SIP-8 package measuring just
21.9 x 11.2 x 9.6 mm (0.86 x 0.44 x 0.38 inches), the
converters are up to 89 % efficient and have a power
density of 44 Watts per cubic inch. With their high
efficiency, no additional heat sink components or forced
airflow is required, ensuring that the converter occupies
the smallest footprint possible, a key criteria of today’s
space constrained designs.
The series offers two 4:1 input range options of either
+ 9 to + 36 VDC or + 18 to + 75 VDC, covering all the
popular nominal input voltages of + 12, + 24 and + 48
VDC. Single output models are available with + 3.3, + 5,
+ 9, + 12, + 15, or + 24 VDC. Duals provide +/- 5, +/- 12
or +/- 15 VDC. No minimum load is required.
Input to output isolation is rated at 1.5k VDC across the
range, and optionally, 3k VDC isolation is available on
–H models. Suiting use in most environments, the ITZ
series can operate across the extended temperature
range from – 40 to + 85 degrees C and deliver the full
output power up to +60 degrees. A remote on/off function
provides the ability to externally control the converter
such as for sequencing start-up or automatically
powering it on or off. All model meets EN55032 level A
for conducted and radiated noise without any additional
components.
Typical applications for the ITZ series include mobile,
portable and wireless products, and any low power
use case where isolation and DC voltage conversion is
required.
The series is available fromDigi-Key, element14, Farnell,
RS Components, approved regional distributors, or
direct from XP Power and come with a 3-year warranty.
Reinforced isolator with integrated power
offers industry’s highest efficiency, lowest
emissions
Texas Instruments (TI) (NASDAQ: TXN) today
introduced a new single-chip reinforced isolator with
integrated power that offers 80 percent higher efficiency
than existing integrated devices. With the industry’s most
efficient power transfer, lowest radiated emissions and
highest immunity this new reinforced isolator supports
reliable operation of industrial systems, including factory
automation, grid infrastructure, motor control, isolated
power supplies, and test and measurement equipment.
Compared to discrete solutions, the ISOW7841
integrates both isolated data and power, enabling a
