16A POL DC-DC Converter Features 94% Efficiency

SAN DIEGO, CA (April 18, 2008) - Lambda has expanded its range of point-of-load (POL) DC-DC converters with the launch of the iAD series of 16-Amp non-isolated, single inline package (SIP), thru-hole mounted devices. Featuring a DOSA compatible pin-out, the iAD series addresses a broad range of applications including telecom, computer, datacom, medical and industrial equipment. These compact units are only 2.0" L x 0.55" H x 0.31" W.

With its ultra wide input range from 6V to 14V, the iAD series are particularly well-suited for powering today's diverse range of loads in a variety of architectures including distributed power and non-regulated 4:1 and 5:1 bus converter systems. Furthermore, its broad output adjustment range from 0.8V to 5.5V, its maximum output current of 16A and its ability to start into a pre-biased load make it especially useful in ASIC, FPGA and other applications where multiple voltages may be required.

Special attention has been paid to the electrical design to gain a high power conversion efficiency of up to 94%. Combined with careful component layout, this allows the iAD series to provide better thermal performance than many similar devices. This enables the designer to benefit from higher output power for a given thermal environment, or lower thermal stress for the same output power. Using proven circuitry, the low component count provides greater reliability, a calculated MTBF of greater than 13.7 million hours, and a more cost-effective solution than other modules on the market.

The iAD POL converter's standard features include fixed-frequency operation for reduced EMI/RFI noise, remote sense, remote on/off, flexible output voltage sequencing, auto-recovery of input under-voltage and output over-current protection circuitry. Available options include: Negative polarity on/off, no output voltage sequencing, industry standard narrow 9.6V to 14V input voltage range and shorter thru-hole pins at 0.13" (standard pin length is 0.20”).

Safety approvals include UL60950, VDE 0805, CB scheme IEC950, CE Mark EN60950. All models carry a three-year warranty.

The iAD series are available now and priced from $11.60 each in 1k-unit quantities. For more information visit Lambda’s web site at www.lambdapower.com.
