Enpirion was founded in 2001 by a dedicated group of engineers with expertise in power management architecture, power semiconductor devices, and high frequency magnetic materials. The core research and development behind our products was begun a decade earlier in the Power Silicon and Advanced Magnetics Groups within Bell Laboratories.  The name Enpirion is derived from the Greek words meaning on silicon. Enpirion is today delivering its Power Systems on Silicon (PSOS) products to some of the largest customers around the globe.

To provide customers with high performance power conversion solutions offering the smallest footprint, lowest part count, and the highest speed in the industry at a competitive BOM (bill-of-materials) cost.

Enpirion is an environmentally friendly company. From the beginning all Enpirion products have been lead-free and RoHS compliant by design, and compatible with high temperature manufacturing lines.

Enpirion makes the industry's smallest power system on Silicon (PSoS) - the first ultra-integrated all-silicon DC-to-DC converter, and the first to feature an integrated inductor.  Enpirion's patented approach capitalizes on semiconductor geometry advances that enable a 10x switching-frequency improvement - integrating a PWM controller, power FETs, compensation circuitry, and magnetic components into a single turnkey IC package.

Enpirion manufactures a growing line of Switch-mode DCDC converters with integrated inductor.  Integration of the inductor sets Enpirion products apart from those of our competitors.  The layout and placement of the inductor is one of the most common reasons for power IC related failures.  Enpirion solves this problem, reduces foot print, reduces part count, and reduces noise associated with switch-mode power conversion.  Applications include high volume consumer products such as mobile phones, portable game players, MP3 and personal media players, as well as data networking, telecoms, user terminal equipment such as set top box, and of course notebook and desktop PC.
