Low profile for dual-output convertors
C and D Technologies (NCL) reckons its latest NKA series industrial temperature range subminiature DC/DC convertors are the world's lowest profile 1W, 3kV DC isolated dual-output devices
The new NKA 1W DC/DC convertors are supplied in subminiature, industry standard 14-pin DIP package styles that deliver a board mounting height of just 5.4mm and a board mounting area of 19.5 x 9.8mm. Ideal for height-limited applications where a dual DC output is required from a single DC rail, the NKA convertors allow any distribution of load across the outputs as long as the total does not exceed 1W.

Devices in the NKA series are available for 3.3, 5 and 12V input voltages.
The 3.3V input voltage parts offer output voltage options of 12 and 15V, while 5 and 12V input parts are can be supplied with output voltage options of 5, 9, 12 and 15V.
In all cases 3kV DC galvanic isolation between input and outputs helps to significantly reduce switching noise.
As well as a reduced profile, the new NKA convertors can also reduce component count as they are capable of delivering their full 1W output across the -40 to +85C industrial temperature range without the need for additional components or external cooling.
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.
All the new NKA devices are supplied in fully encapsulated, UL94V0-compliant packaging and employ a toroidal magnetic construction that minimises external fields and ensures suitability for applications with high component densities.
Typical line regulation for each device is rated at 1%, and typical ripple and noise ratings are as low as 30mA (peak-peak).
NKA DC/DC convertors have unit pricing of under $5.00 for OEM quantities.
As well as the standard devices in the series, C and D Technologies (NCL) can also design and manufacture custom parts based on the NKA technology.
