Lambda has added to its range of point of load converters with the launch of the iAD series of non-isolated, single inline package, through-hole mounting devices. Featuring a DOSA compatible pin out, the iAD series addresses a broad range of applications from telecoms through to industrial equipment.

With its wide input range from 6 to 14V, the iAD12016A008V is particularly well-suited for powering today's diverse range of loads in a variety of architectures including distributed power, for example regulated 9V or 12V bus rails, 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 power of 80W and its ability to start into a pre-biased load make it especially useful in ASIC/FPGA and other applications where multiple voltages can be present.

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 and a more cost-effective solution than other modules on the market.

The iAD POL converter's standard features include fixed frequency operation, remote sense, remote on/off, flexible output voltage sequencing, auto-recovery of input under voltage and output over current protection circuitry. Negative polarity on/off, no output voltage sequencing, an industry standard narrow 9.6V to 14V input voltage range, and short 0.13” (3.3mm) pins are offered as options.

Safety approvals include UL60950 (U.S. and Canada), VDE 0805, CB scheme (IEC950), and CE Mark (EN60950). All models carry a three-year limited warranty.
