dsPIC33EP ‘GS’ Family of Digital Signal Controllers

Digital Power | Dual Partition Flash | Live Update | Dual CAN | High-Speed PWM | High-Speed ADC | Scalable

The dsPIC33EP "GS" family delivers the performance needed to implement more sophisticated non-linear, predictive and adaptive control algorithms at higher switching frequencies in digital power applications. 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. Compared with the previous generation of dsPIC33FJ ‘GS’ DSCs, the dsPIC33EP ‘GS’ devices 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 key features of this family include up to five 12-bit Analog-to-Digital Converters (ADCs) with as many as 22 ADC inputs, providing total throughput of 16 Mega samples per second (Msps) with a 300 ns ADC latency. For higher-precision designs, these devices also include 12-bit Digital-to-Analog Converters (DACs) for each of the four analog comparators. The 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 cost and board space.
