Microchip expands its 16-bit Digital Signal Controller family for digital power supplies

Microchip has expanded its 16-bit dsPIC Digital Signal Controller (DSC) portfolio for digital power-conversion applications with four times the memory capacity compared to its present dsPIC devices. These new DSCs can be configured for different topologies and offer up to 18 channels of Pulse-Width-Modulators (PWMs) with 1 nanosecond resolution.


The on-chip peripherals available on 16-bit dsPIC33F 'GS' Series include high-speed PWMs, 10-bit Analog to Digital Converters (ADCs) and analog comparators. The dsPIC33F 'GS' family are suitable for applications such as induction cooking, uninterruptable power supplies, solar and pure sine-wave inverters, intelligent battery chargers, power factor correction, HID lighting, fluorescent lighting, LED lighting, and AC-DC and DC-DC power converters.

"Microchip further extends its industry leadership with this family of digital-power DSCs," said Sumit Mitra, vice president of Microchip's High Performance Microcontroller Division. "These new devices enable a broader set of digital-power applications that require more communication and control of more complex systems."

The eight new dsPIC33F 'GS' series digital-power DSCs enable digital control loops with 12 to 18 high-speed, 1 nanosecond (ns) resolution PWMs and one or two 10-bit, on-chip ADCs, providing 2 to 4 Million samples per second (MSPS) for low latency and high-resolution control. They range from 64 to 100 pins and 32 to 64 KB Flash memory.

Package: dsPIC33FJ32GS406, dsPIC33FJ64GS406, dsPIC33FJ32GS606 and dsPIC33FJ64GS606 are available in 64-pin TQFP and 9x9 mm QFN packages. The dsPIC33FJ32GS608 and dsPIC33FJ64GS608 are available in an 80-pin TQFP package. The dsPIC33FJ32GS610 and dsPIC33FJ64GS610 are available in a 100-pin TQFP package.
