dsPIC33EP "GS" Family for Digital Power Applications
Higher Performance Enables More Sophisticated Algorithms
The dsPIC33EP "GS" family delivers 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. Compared with the previous generation of DSCs, the new 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.
More Integration Saves Cost and Board Space
Other key features of this family include up to five 12-bit ADCs with as many as 22 ADC inputs, providing total throughput of 16 Mega samples per second (Msps) with a 300 ns ADC latency. The dsPIC33EP "GS" devices include 12-bit DACs for each of the four analog comparators, for higher-precision designs. 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.
Variants from this new digital-power-optimized DSC family are available in an industry's-smallest, 4 x 4 mm UQFN package for space-constrained designs. Products in this family range from 28 to 64 pin options and 16 to 64KB Flash.
This new dsPIC33EP "GS" family includes 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.
Easier Digital Power Conversion Designs
The dsPIC33EP "GS" family is supported by the Digital Power Starter Kit (part # DM330017-2, $129.99), as well as several helpful software tools. Microchip's new Digital Compensator Design Tool helps engineers calculate the optimum compensator coefficients required to maximize the performance of their designs.
