Microchip Expands dsPIC DSCs for Digital Power and Lighting Applications
Microchip today announced a new family of dsPIC33 “GS” Digital Signal Controllers — the dsPIC33FJ09GS302 family. This is an expansion of Microchip’s dsPIC DSC portfolio that adds lower-cost options for digital-power conversion. The new family of DSCs also brings new features while lowering power consumption, enabling higher efficiency in AC-DC and DC-DC power supplies, HID & LED lighting, solar inverters, and other power conversion applications.
The five-member dsPIC33FJ09GS302 family is optimized for digital-power applications via integrated high-speed ADCs, a zero-wait-state signal processing core, and flexible high-resolution PWMs. These peripherals are integrated for streamlined interoperation, enabling sub-microsecond digital control loops. Other key features of this family include on-chip analog comparators with programmable hysteresis and rail-to-rail operation, and an on-chip PMBus™ address selection current source to reduce external components. These new DSCs offer the lowest power dissipation of any of the GS family members, and are the first available in a 20-pin SSOP package and the even smaller 36-pin VTLA package, which has a 5x5 mm footprint.
“Customer adoption of our dsPIC33 GS family has been outstanding, with design wins in a wide range of power products, globally,” said Mitch Obolsky, vice president of Microchip’s MCU16 Division. “The new dsPIC33FJ09GS302 family builds upon that success by enabling the efficiency of full digital control in more cost-sensitive, lower-wattage power-conversion applications.”
