ELECTRONICS: TDK-Lambda expanded its range of point-of-load (POL) DC-DC converters with the launch of the iBD series of 7-Amp non-isolated, single- inline-package (SIP), thru-hole mounted devices. Featuring a DOSA compatible pin-out, the iBD series addresses a broad range of applications including telecom, computer, datacom, medical and industrial equipment. These tiny units are only 1.0 x 0.50 x 0.33 inch. With its ultra wide input range from 6V to 14V, the iBD series are particularly well-suited for powering today’s diverse range of loads in a variety of architectures including distributed power and 4:1 and 5:1 unregulated bus converter systems. Furthermore, its broad output adjustment range from 0.8 to 5.5V, its ability to start with a pre-biased output, and its maximum output current of 7A 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 92 percent. Combined with careful component layout, this allows the iBD 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.
The iBD POL converter’s standard features include fixed-frequency operation for reduced EMI/RFI noise, 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, VDE0805, and CB scheme (IEC60950). All models carry a three-year warranty and are RoHS compliant.
The iBD series are available now and priced from $9.67 each in 1000-unit quantities. More information can be found at TDK-Lambda’s website.
