TDK Innoveta Inc. is expanding the quarter brick iQP-series product line, adding two more models of 3.3Vdc/70A and 2.5Vdc/80A output. According to the company, the isolated, wide input range (36-75Vdc), tightly regulated converters offer the highest usable power among high power quarter bricks. The iQPseries employs the industry standard Double-P quarter brick pin-out. The converters are RoHS compliant.
Adding 3.3Vdc and 2.5dcV outputs to the family, iQP-series can offer full line up from 1.2V/100A to 12V/25A with tight regulation. The iQP's newly developed integrated magnetic components and unique structure, which combines Double-P and open frame IMS (insulated metal substrate) based designs, allows ultra high current while maintaining good thermal performance. The iQP 3.3V/70A can provide up to 49A and iQP 2.5V/80A can provide up to 53A at 65°C, 200LFM without a heat sink. It is suited for limited space and power-hungry applications such as high-end routers, switches, servers, storages, and many industry applications.
The iQP's tightly regulated output, pre-bias tolerance, and well-behaved start up make it suitable for feeding power directly to complex integrated circuits. iQP's robust control has less interaction with downstream converters, reducing the required bus capacitance in bus architectures such as 3.3Vdc bus. Standard features include remote sense, remote on/off, pre-biased start up, wide output voltage trim range and auto recovery circuits to fully protect against input over-voltage and under-voltage.
Over-temperature, output over-current, and output over-voltage protection features are also standard and can be ordered as either latching or non-latching. Safety approvals include UL60950 (U.S. and Canada), VDE 0805, CB scheme (IEC950) and CE Mark (EN60950). In OEM quantities of 1,000 pieces, the unit price of the iQP48070A033V (3.3V/70A), iQP48080A025V (2.5V/80A) is $95. Samples are available now.
