Maxim Integrated Products announced its entry into the fast-growing digital power market with its patented InTune™ brand digital power technology; it is based on “state-space” or “model-predictive” control rather than proportional-integral-derivative (PID) control used by competitors.
Maxim’s InTune digital power technology performs an automatic compensation routine that is based on measured parameters, which enables the construction of an internal mathematical model of the power supply including the external components. The result is a switching power supply that achieves the highest possible dynamic performance while guaranteeing stability. Furthermore, this information enables several proprietary algorithms that optimize efficiency across a wide range of operating conditions. Maxim’s InTune digital power technology requires up to 5x lower bias current than competing devices, further improving overall efficiency for applications such as networking, telecom, and servers.
