Telecommunications

The world is becoming an increasingly interconnected place, and telecommunications products and systems help to enable this connectivity. The smartphones that are replacing PCs, laptops, cameras, and even GPS systems are crammed with electronic components for voice communications, texting, email, web browsing, social media interaction, navigation, and imaging. Supporting are these functions are the earthbound, airborne, and underwater systems that comprise the telecommunications infrastructure: base stations, transmission towers, satellites, submarine communications cables, modems, line cards, and more, all of which require electronic components.

Non-isolated point-of-load converters are generally used in intermediate bus architectures to step down the bus voltage. This multi-stage power conversion is widely implemented in telecom, computer, and consumer appliances. The POL modules or on-board POL circuits can be placed close to the payload, thereby adding flexibility to the design.
