DC-DC Converters provide extended temperature operation.

Press Release Summary:



IC-Style DC-DC Converters are 3.3 V-input surface mount devices with footprints of 1.64 cm2 and dual isolated outputs of either 12 or 15 V. They are fully compliant with CECCO0802 standard for reflow soldering at 280°C. Each device combines multi-layer ceramic capacitors with internal SMD construction. Converters feature l kVdc isolation between input and output. Load regulation is typically 11%, while typical ripple current is 41 mA peak-to-peak.

Miniature IC-Style DC-DC Converters Offer Extended Temperature, Improved Reliability and Simplified Assembly In Low-Voltage Applications


9th October 2001, Raleigh, North Carolina - C&D Technologies
(NCL) has expanded its family of IC-style DC-DC converters by
launching two miniature, 3.3V-input, dual-output parts that provide extended temperature operation and improved reliability while saving board space and simplifying final assembly.

Ideal for low-voltage applications where analogue circuits need to be combined with the latest low-voltage processor technologies, the new 3.3V-input NTA DC-DC converters are surface mount devices with footprints of just 1.64cm2 and dual isolated outputs of either 12 or 15V. The converters are fully compliant with the CECCO0802 standard for reflow soldering at 280°C, which allows them to be mounted at the same time as conventional ICs. This significantly simplifies final assembly by
eliminating the need for additional mounting and solder processes. Component count is reduced and assembly is further simplified by the fact that the converters can deliver full specification performance at between -40°C and 85°C without the
need for a heatsink or other external components.

C&D Technologies' NTA DC-DC converters are based on advanced transfer molding techniques and the latest lead frame technology. Each device combines multi-layer ceramic capacitors with an internal SMD construction, resulting in optimum reliability levels and a rated mean time to failure (MTTF) up to 1.69 million hours. In addition, a toroidal magnetics construction helps designers to address EMC requirements by minimizing radiated noise during operation.

The new converters feature lkVDC isolation between input and output and allow any distribution of load across the dual outputs providing that the total does not exceed 1 W. Load regulation is typically 11%, while typical ripple current for the
devices is 41 mA peak-to-peak.

Packaged in UL 94V-0 material, the new NTA DC-DC converters are available in tape-and-reel format and have pin co-planarity in line with the requirements of IEC 191-6:1990.

In addition to the standard devices, C&D Technologies (NCL) can design and manufacture custom parts based on the new 3.3V-input NTA technology. Pricing for the standard parts is $5.31 for 10,000 components.
