C&D Technologies Intros NDT DC/DC Converters
C&D Technologies Inc. (Tucson, AZ) recently expanded its family of miniature, board-mounting, dc/dc converters with the launch of its new NDT isolated, 3W, dual-output, converters, which are suitable for height-constrained applications, including rack-mounted industrial and telecommunications PCBs. The new NDT converters are supplied in a low-profile, 24-pin, DIL package with a board mounting height of just 7mm (0.28in) that conforms to an industry-standard 32.26mm x 14.66mm (1.27in x 0.58in) footprint.
The NDT converters feature nominal input-voltage ratings of 24V or 48V; a wide 2:1 input capability that allows them to handle voltage ranges of 18V to 36V or 48V to 75V, respectively; output-voltage options of 12V or 15V for each nominal input voltage; a power density of 0.90W/cm³; delivery of 3W output power at temperatures up to 85°C without the need for a heatsink or other additional cooling; a flyback oscillator design with isolated feedback; a full operating range of 25 percent to 100 percent of full load; and load and line regulation rated at less than one percent on the positive output.
All members of the NDT family are supplied in fully encapsulated, UL 94V-0-compliant packaging and feature an internal SMD construction that uses multi-layer ceramic capacitors to ensure maximum operating life. The full operating temperature range for the devices is -40°C to +85°C. The NDT dc/dc converters have unit pricing of under $10 in OEM quantities.
