About Us

Empower Semiconductor was founded to solve fundamental problems in power delivery for data-intensive applications.

Traditional power solutions require dozens of discrete components with big footprints, complex designs and deliver power inefficiently with poor response times and inaccuracies. 

Empower’s patented IVR technology integrates dozens of components into a single IC increasing efficiency, shrinking footprints by 3x and delivering power with unprecedented simplicity, speed & accuracy and with zero discrete components. 

This IVR technology addresses a $10B opportunity with a wide range of applications including mobile, 5G, AI and data centers.  The company is based in San Jose, CA and is led by a team of highly experienced power experts and executives.
