Microchip launched the 14-member dsPIC33EP “GS” family of Digital Signal Controllers (DSCs), which delivers the performance needed for more sophisticated non-linear, predictive and adaptive control algorithms at higher switching frequencies. These advanced algorithms enable power supply designs that are more energy efficient and with better specifications. Higher switching frequencies enable the development of physically smaller power supplies that offer higher densities and lower costs. Compared with the previous generation, the new DSCs provide less than half the latency, when used in a three-pole three-zero compensator, and consume up to 80% less power in any application.
The new dsPIC33EP “GS” family includes advanced features such as Live Update Flash capability, especially helpful for high-availability or “always-on” systems. It can be used to change the firmware of an operating power supply, including the active compensator calculation code, while maintaining continuous regulation.
