Sixteen-Amp POL DC/DC Converter Features 94 Percent Efficiency
Lambda has expanded its range of point-of-load (POL) DC/DC converters with 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 range of applications including telecom, computer, datacom, medical and industrial equipment. These units are 2.0” × 0.55” × 0.31”. With its wide input range from 6V to 14V, the converters are suited for powering a diverse range of loads in a variety of architectures including distributed power and non-regulated 4:1 and 5:1 bus converter systems. 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 useful in ASIC, FPGA and other applications where multiple voltages may be required. The converters are designed to gain a high power conversion efficiency of up to 94 percent. Combined with careful component layout, this allows the device to provide desirable thermal performance. According to the company, designers can benefit higher output power for a given thermal environment, or lower thermal stress for the same output power. UThe low component count provides reliability with a calculated MTBF of greater than 13.7 million hours. 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”). The converters are priced from $11.60 each in 1k-unit quantities.
