Original Press Release:



Isolated 2W Dual Output DC-DC Converters Offer Industry's Lowest Profile



8th October, 2002, Tucson, Arizona - With a height of just 5.5mm
(0.22"), the NTH series from C&D Technologies are the industry's
lowest profile 2W, dual isolated output DC-DC converters. Ideal for rack-mounted industrial and telecommunications designs where height is restricted, the NTH devices also minimise board space thanks to a very small mounting footprint of just 3.16cm2 (0.49inches²).

The new surface mount DC-DC converters are available with input voltages of either 5V or 12V and dual isolated output options of 5V, 9V, 12V or 15V. In all cases isolation between input and output is rated at 1kVDC. A wide operating temperature range allows the devices to deliver their full 2W performance between -40°C and 85°C without a heatsink.

By employing leadframe technology and transfer moulding techniques, the new NTH DC-DC converters bring the benefits of IC style packaging to hybrid circuitry. All devices are lead-free compatible and offer a guaranteed pin coplanarity of 0.1mm in accordance with IEC191-6:1990. Full compliance with the CECC00802 standard for reflow soldering at to 280°C allows the converters to be placed and soldered alongside conventional ICs.

The NTH converters operate with efficiencies up to 84% and have a total power density of 1.54W/cm³ (25.67W/inch³). Maximum internal power dissipation is specified as 550mW. Typical line regulation is 1%, while load regulation is 5% for the 5V output converters and 3% for all other devices.

Supplied in fully encapsulated, UL 94V-0-compliant packaging, NTH DC-DC converters use an internal SMD construction and multi layer ceramic capacitors, which contribute to an MTTF rating of 2.1 million hours.

Unit pricing for the NTH converters is under $7.00 in OEM quantities.
