Tiny DC/DC convertors save power system
space
A new 3.3V-input subminiature 1W dual-output DC/DC convertor offers space and component count savings to low-voltage distributed power architectures requiring dual DC outputs from a single DC rail.
The latest 3.3V-input subminiature 1W dual-output DC/DC convertors from C and D Technologies (NCL) offer significant space and component count savings to low-voltage industrial distributed power architectures requiring dual DC outputs from a single DC rail Featuring a PCB footprint of 16.55 x 5.95mm, the dual-output NKA03 3.3V DC/DC convertors are supplied in a subminiature SIP packaging with an industry standard pin out and are available with outputs of either 12 or 15V

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.
The convertors offer maximum design flexibility by allowing any distribution of the load across the outputs as long as the total does not exceed 1W.
Galvanic isolation between input and outputs of 3kV DC ensures minimum switching noise.
In addition to saving space through their small footprint, the low-voltage NKA convertors also contribute to simplified board layout and reduced component count by delivering full load performance from -40 to +85C without the need for a heatsink or other external cooling.
Typical line regulation for the devices is rated at 1%, while typical ripple and noise current ratings are just 30mA (peak-to-peak).
The new low-voltage DC/DC convertors are supplied in fully encapsulated, UL94V0-compliant packaging and use a toroidal magnetic construction that minimises external fields and makes the devices ideal for applications with high component densities.
An internal SMD construction that uses multilayer ceramic capacitors rather than electrolytic or tantalum alternatives contributes to a long operating life and an MTTF rating of up to 1.6 million hours.
Unit pricing for the low-voltage NKA devices is under $5.00 for OEM quantities.
In addition to the standard, 'off-the-shelf' parts, C and D Technologies (NCL) can also offer custom NKA solutions. Request a free brochure from Murata Power Solutions ...
