DC to DC Power Supplies (Converters)
Converters minimize need for external components.
Press Release Summary:
Miniature, non-isolated, point-of-load dc/dc converters reduce board space and design complexity by eliminating need for additional components. LSM2 surface mount and LSN2 through-hole modules can power CPUs, programmable logic, and mixed-voltage systems with minimum noise and heat. With input voltage of 2.5-5.5 V and 9-14 V, they are suitable for use in distributed power and intermediate bus architectures. DOSA and RoHS-6 compliant converters feature user programmable outputs of 0.75-5 V.
Original Press Release:
Miniature, Programmable POL Converters Minimize Need for External Components
High-efficiency, DOSA-compliant non-isolated (POL) modules
o User programmable outputs of 0.75V to 5.0V
o No heatsinking or external filter components required
o Surface mount and SIP (through-hole) models available
January 27th, 2006, Mansfield, MA - C&D Technologies (NYSE: CHP) has introduced a series of very high efficiency non-isolated point-of-load (POL) DC/DC converters that reduce board space and design complexity by eliminating the need for additional components including - in most applications - heatsinks and external filter circuits.
Combining miniature form factors with high levels of on-board functionality and efficiency levels to 95.5%, the new LSM2 (surface mount) and LSN2 (through-hole) modules can power CPUs, programmable logic and mixed-voltage systems with minimum noise and heat. In addition to eliminating the need for cooling, low temperature operation also improves reliability and extends product life.
Converters in the new series offer input voltage range options of 2.5-5.5V and 9-14V and are ideal for use in distributed power and intermediate bus architectures. The range comprises a total of six modules (output current options of 6A, 10A and 16A for each input voltage) and can deliver up to 52W of output power (LSN2-T/16-D12). The rated output power is available at up to +70ºC ambient with 200LFM airflow. All devices feature user-selectable outputs of 0.75V to 5V. Voltage selection is made with either an external programming resistor or by a DC voltage applied to the trim pin.
The entire family of converters is fully compliant to the Distributed-power Open Standards Alliance (DOSA) specification. All of the converters are also designed for compliance with the RoHS-6 standards, and will withstand high temperature attachment processes required for assembly in an RoHS-6 application. RoHS-6 compliant modules will be available Q1- 06.
Standard features include a 'Power Good' output, remote On/Off control with either positive or negative logic, a selectable start-up configuration for sequencing or tracking multiple voltages, and an output sense pin for compensating IR drops. On-board self-protection functionality includes output short circuit protection 'hiccup' shutdown, OVP and OCP, and over-temperature shutdown.
The LSM2 and LSN2 family have UL 60950, CSA-C22.2 No. 234, and EN60950 safety approvals. Pricing for 1,000 pc quantities (16A) is approximately $13 each and products are available for immediate delivery.

C&D Technologies, Inc. is a technology company that produces and markets systems for the conversion and storage of electrical power, including telecom/industrial batteries, rectifiers and electronics. This specialized focus has established the company as a leading and valued supplier of products in two major categories - reserve power systems and electronic power supplies. Corporate headquarters are in Blue Bell, Pennsylvania, USA and the company is traded on the NYSE under the symbol 'CHP'.
The Power Electronics Division of C&D Technologies, Inc. has its headquarters in Mansfield, Massachusetts, USA, with manufacturing in USA, Mexico, UK and China plus sales locations in the USA, UK, France, Germany, China and Japan. The division designs, manufactures and distributes DC/DC converters, AC/DC power supplies, magnetics, Data Acquisition devices and panel meters, and offers these products in custom, standard and modified-standard variations. These products, which are built to exacting requirements in ISO9000:2000-approved facilities, are typically used worldwide by Original Equipment Manufacturers (OEMs) within telecommunications, computing, industrial and other high-tech applications.
In 2004 the product portfolio as well as the global design and manufacturing capabilities of the Power Electronics Division were significantly enhanced as a result of three key acquisitions. In May 2004, C&D acquired UK-based Celab Limited, a designer and manufacturer of power conversion products for military, cable television and high-end telecommunications applications. In June 2004, the company acquired Datel, Inc., a US-based producer of medium-power DC/DC converters, data acquisition products and digital panel meters. In September 2004, C&D completed the acquisition of CPS, the former Power Systems Division of Celestica, Inc., a Canadian manufacturer of DC/DC and AC/DC power supplies.
