3W convertors keep
their heads down onboard
Two new miniature isolated 3W DC/DC convertors with wide 2:1 input ranges and board-mounting profiles of just 7mm are ideal for designs where space above the PCB may be limited
Two new miniature, isolated 3W DC/DC convertors with a wide 2:1 input range and a board-mounting profile of just 7mm are ideal for rack-mounted telecommunications applications and other designs where space above the PCB may be limited. Featuring an industry-standard footprint, the new NDY2403 and NDY4803 convertors from C and D Technologies (NCL) provide a single, regulated 3.3V output and have an input-to-output isolation rating of 1kV DC.

Low profile inductors for line-filtering purposes
Surface-mount inductors are suitable for use in low-power line-filtering applications in consumer, industrial and telecomms applications
The NDY2403 can handle input voltages from 18 to 36V, while the NDY4803 is suitable for input voltages from 36 to 72V.
Each convertor will deliver its full 3W output at temperatures from -40 to +85C without the need for a heatsink.
Each of the new DC/DC convertors incorporates a flyback oscillator design with isolated feedback to ensure regulation over the full operating range of 25% to 100% of full load.

Typical load and line regulation for each device is rated at 0.6% and 0.05%, respectively, while maximum ripple and noise ratings are just 180mV (peak-to-peak).
The new DC/DC convertors incorporate continuous short-circuit protection and are based on an SMD construction that contributes to MTTF ratings in excess of 1.6Mh.
Both devices are supplied in a fully encapsulated, UL94V0-compliant package with a footprint of 4.73cm2 and a power density of 0.90W/cm3.
NDY DC/DC convertors have unit pricing of under $9.00 for OEM quantities.
As well as the standard NDY devices, C and D Technologies (NCL) can design and manufacture custom parts based on the NDY technology.
