The dsPIC33F “GS” family supports applications such as induction cooking, Uninterrupted Power Supplies (UPSs), inverters, intelligent battery chargers, power factor correction, HID lighting, fluorescent lighting, LED lighting, and AC-to-DC, as well as DC-to-DC power-conversion applications.
The dsPIC33F “GS” DSCs are available in 28- to 100-pin packages, with 16 - 64K of Flash. The on-chip ADC operates at up to 4 Msps, and the PWM peripherals provide up to 1 nanosecond resolution, with modes supporting all power-conversion topologies. In addition, the DSCs feature up to four on-chip analogue comparators with integrated on-chip digital-to-analogue converters, enabling designers to set trip levels dynamically. The analogue comparators can be used to directly control the PWM functions.
As the new dsPIC33F “GS” DSCs are 100% compatible with existing dsPIC33F “GS” devices, all existing tools and reference designs are supported. This includes Microchip’s Digital LED Lighting Development Kit (DM330014) priced at $249; Buck/Boost Converter PICtail™ Plus Daughter Board (AC164133) priced at $89.99; and 16-bit 28-pin Starter Board (DM300027) priced at $79.99. In addition, Microchip offers the most comprehensive set of royalty-free digital-power reference designs in the industry, including those for AC-to-DC power supplies, DC-to-DC converters, solar inverters, UPSs, Interleaved PFC, and HID lighting.
The dsPIC33F “GS” DSCs are available today for sampling and volume production in 28- to 100-pin QFN, SOIC, SPDIP, TQFP and VTLA packages.
