Point-of-load convertors keep cool and
quiet
New high efficiency nonisolated point-of-load DC/DC convertors reduce board space and design complexity by eliminating the need for additional components.
C and D Technologies has introduced a series of very high efficiency nonisolated point-of-load DC/DC convertors that reduce board space and design complexity by eliminating the need for additional components including - in most applications - heatsinks and external filter circuits Combining miniature form factors with high levels of onboard functionality and efficiency levels to 95.5%, the new LSM2 (surface mount) and LSN2 (through-hole) modules can power CPUs, programmable logic and mixed-voltage systems with minimum noise and heat

Convertors satisfy current-hungry applications
Isolated wide-input-range DC/DC convertors deliver 50-60W of power from a standard 40.6 x 50.8 x 10.16mm PCB-mounting open-frame package.
Eighth-brick convertors power up to 100W
Murata Power Solutions has a new series of cost-effective eighth-brick DC/DC convertors.
In addition to eliminating the need for cooling, low temperature operation also improves reliability and extends product life.
convertors in the new series offer input voltage range options of 2.5-5.5 and 9-14V and are ideal for use in distributed power and intermediate bus architectures.
The range comprises a total of six modules (output current options of 6, 10 and 16A for each input voltage) and can deliver up to 52W of output power (LSN2-T/16-D12).
The rated output power is available at up to +70C ambient with 60m/min linear airflow.
All devices feature user-selectable outputs of 0.75 to 5V.
Voltage selection is made with either an external programming resistor or by a DC voltage applied to the trim pin.
The entire family of convertors is fully compliant to the Distributed-power Open Standards Alliance (DOSA) specification.
All of the convertors are also designed for compliance with the RoHS-6 standards, and will withstand high temperature attachment processes required for assembly in a RoHS-6 application.
RoHS-6 compliant modules will be available in Q1 2006.
Standard features include a power good output, remote on/off control with either positive or negative logic, a selectable start-up configuration for sequencing or tracking multiple voltages, and an output sense pin for compensating IR drops.
onboard self-protection functionality includes output short circuit protection hiccup shutdown, OVP and OCP, and overtemperature shutdown.
The LSM2 and LSN2 family have UL 60950, CSA-C22.2 No 234 and EN60950 safety approvals. Request a free brochure from Murata Power Solutions ...
