Digital Power  

Digital power is any energy conversion system where digital control techniques apply to power products, and where monitoring, communication and supervisor functions come as extension of the main digital control loop or in conjunction of the main analog control loop.

From low to high power applications, digital power management and control, mainly applied to SMPS, enable higher system efficiency and power density, faster control loop, increased system-level integration, improved system-level reliability, monitoring and safety, reduced time to market.

ST’s extensive digital power portfolio fits the different needs of digital power designers and accelerates their development. ST’s digital power solutions are fully supported with evaluation boards, technical documentation, eDesignSuite software configurator and design tool.
