dsPIC33EP GS Digital Signal Controllers Microchip dsPIC33EP GS Digital Signal Controllers (DSCs) feature a 70-MIPS dsPIC® DSC core with integrated DSP and enhanced on-chip peripherals. These DSCs are designed to deliver the performance needed to implement 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 have better power supply specifications. Higher switching frequencies enable the development of physically smaller power supplies that offer higher densities and lower costs.
