The Microchip dsPIC33F GS 16-bit dsPIC digital signal controllers (DSC) can be configured for a variety of topologies. The eight new DSCs offer up to 18 channels of Pulse-Width-Modulators (PWMs) with 1 nanosecond resolution, enabling a number of completely independent digital control loops. The dsPIC33F GS DSCs start at $2.93 each in 10,000-unit quantities. The dsPIC33FJ32GS406, dsPIC33FJ64GS406, dsPIC33FJ32GS606 and dsPIC33FJ64GS606 are available in 64-pin TQFP and 9×9 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.
Microchip’s 16-bit dsPIC33F GS Series DSCs provide on-chip peripherals designed for high-performance, digital power supplies. On-chip digital power peripherals include high-speed PWMs, ADCs and analog comparators. The dsPIC33F GS family supports 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.
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. These DSCs feature interactive peripherals that both minimize the intervention of the processor and are able to handle the real-time needs of high-speed current-mode control.
