This new dsPIC33EP “GS” product family includes advanced features such as Live Update Flash, making it particularly useful for systems that are highly available and remain always on. Live Update maintains continuous regulation while also being usable for changing the firmware of the power supply in operation, including active compensator calculation codes. This new DSC family, optimized for digital power, is available in the industry's smallest 4 x 4 mm UQFN package for space-constrained designs.

This product family features up to five 12-bit ADCs with as many as 22 ADC inputs, providing an ADC latency of 300 ns with a total processing speed of 16 megasamples per second (Msps). The dsPIC33EP “GS” device incorporates a 12-bit DAC in each of the four analog compensators to enable high-precision designs. Additionally, two on-chip programmable gain amplifiers can be used for current sensing and other precision measurements. Since these advanced analog amplifiers are included within the device, the number of required external components is reduced, resulting in lower costs and board space. Combining these features and outstanding overall performance, the dsPIC33EP “GS” product family is highly suitable for a wide range of applications, including computers and communications (e.g., AC/DC and DC/DC power supplies), industrial (e.g., solar inverters, LED lighting, HID lighting, battery chargers, projectors, and welding machines), and automotive (e.g., LED and HID headlights, DC/DC converters).

"Microchip's existing dsPIC33 digital power product family has been well-received by customers and has been adopted in the design of a wide range of power conversion products worldwide," said Joe Thomsen, Vice President of Microchip's MCU16 Product Business Unit. "Building on this success, the new dsPIC33EP 'GS' product family will provide higher performance and integrated features to enable higher efficiency and smaller form factors in next-generation designs."

Development support

Microchip’s MPLAB® Starter Kit for Digital Power (part number DM330017-2) supports the dsPIC33EP “GS” family, and this kit allows you to explore widely used digital power conversion topologies using the new dsPIC33EP “GS” family.

Microchip's new digital compensator design tool helps calculate the optimal compensator coefficients needed to maximize design performance. This tool, provided free of charge, is combined with Microchip’s compensator software library and numerous royalty-free dsPIC33 reference designs to make it easier than ever to develop digital power conversion applications.

In addition, Microchip, in collaboration with Biricha Digital, offers an in-depth digital power design workshop that helps both analog power device developers and embedded system programmers utilize full digital control capabilities in their designs.
