Picor Introduces New 360 Micro-Ohm MOSFET for Low Voltage Power Applications

Picor, a subsidiary of Vicor Corp., announced the PI5101, said to be the industry-first MOSFET with "Micro-Ohm" on-state resistance. Well suited for low voltage, high-current power path management applications, the new µR_DS(on)FET™ device combines the advantages of a very low on-state resistance with thermally enhanced LGA packaging. The PI5101 is a companion product for Picor’s Power Management IC controllers. When combined with a compatible Picor controller, the PI5101 enables what the company says is industry best on-state low power dissipation for applications such as active ORing, hot swap power managers, load switches and high current dc-dc converters.

The PI5101 combines a high-performance 5V 360 Micro-Ohm on-state resistance with a thermally enhanced high-density land grid array package to enable world-class performance in an industry standard SO-8 package footprint. The PI5101 offers unprecedented attributes for DC and switching applications. The PI5101 can replace up to six conventional SO-8 form factor devices for the same on-state resistance, reducing board space by approximately 80%. The device offers unprecedented figure-of-merit for R_DS(on) x Qg, gate resistance (R_G) and package inductance (L_DS), outperforming conventional MOSFETS and enabling very low loss operation. The PI5101 LGA package is fully compatible with industry standard SMT assembly process and is compatible with most off-the-shelf MOSFET controller ICs.

"Picor’s µR_DS(on)FET solutions can substantially reduce power dissipation by up to six times versus conventional MOSFET solutions, while providing superior dynamic performance and eliminating the need for unnecessary thermal management overhead," said Chester Firek, Product Marketing Manager.

The PI5101 is available in a 4.1 x 8 x 2mm thermally-enhanced LGA. Production volumes are available now. Evaluation boards are also available now.
