Enpirion

The company's core business revolves around the design and manufacturing of these PwrSoC DC-DC converters, which integrate components like power switches, inductors, gate drives, and control circuitry into a very small footprint. This high level of integration offers clients significant benefits, including reduced board space, lower electrical noise, enhanced power density, and faster design cycles compared to traditional discrete power supply components. Enpirion's products cater to a broad market, serving designers of FPGAs, ASICs, CPUs, and other semiconductor devices across enterprise servers, storage, telecommunications, and industrial applications. High-volume consumer products like mobile phones and media players were also target applications. Revenue was generated through the sale of these PwrSoC devices.

Enpirion's journey includes several significant milestones. After its founding, the company raised a total of $59 million in funding over four rounds to fuel its growth. It began high-volume production of its PowerSoCs in 2005. A pivotal moment came in May 2013 when Altera Corporation acquired Enpirion for approximately $140 million, aiming to combine Altera's FPGAs with Enpirion's power solutions to offer customers enhanced performance and lower system power. Following the acquisition, Ashraf Lotfi became an Altera Fellow and the chief technologist for the newly formed power business unit. The journey continued when Intel acquired Altera for $16.7 billion in 2015, bringing the Enpirion product line into Intel's Programmable Solutions Group. In late 2020, Intel sold the Enpirion business to Richtek Technology Corp., a subsidiary of MediaTek, for $85 million, allowing Intel to focus on its core FPGA business while enabling Richtek to bolster its offerings for enterprise-level system applications.
