Microchip Technology 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.

The Microchip Technology dsPIC33EP GS DSCs include advanced features such as Live Update Flash capability, which is especially helpful for high-availability or "always-on" systems. Live Update can be used to change the firmware of an operating power supply, including the active compensator calculation code while maintaining continuous regulation.

The dsPIC33EP GS series features up to five 12-bit ADCs with as many as 22 ADC inputs. These devices also include 12-bit DACs for each of the four analog comparators, for higher-precision designs. Two on-chip programmable gain amplifiers can be used for current sensing and other precision measurements. Including these advanced analog amplifiers on the device reduces the number of external components required, thereby saving costs and board space.
