Lambda Releases New 16A POL DC-DC Converter

Lambda has expanded its range of point-of-load (POL) dc-dc converters with the launch of the iAD series of 16A 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. The units measure 2.0 x 0.55 x 0.31".

With its wide input range from 6 to 14V, the iAD series are said to be 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 0.8 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%. This is said to allow the iAD series to provide better thermal performance than many similar devices. This is also said to enable 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 is claimed to provide 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 9.6 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.
