One of the most important features in switched mode power supplies is power density. It is crucial for high-power applications like server and telecom but it is also a key factor for low- to mid-power designs like battery chargers and adapters. Let’s explore the performance of advanced solutions like Infi

U.S. commercial businesses spend over $100 billion on energy annually with much of that consumption coming from building systems such as HVAC, lighting, security, elevators and fire protection.  For example, in a commercial building, lighting alone can account for almost 35% of the total energy used. Experts es
