Microchip Technology Inc. announced a new family of dsPIC33 "GS" Digital Signal Controllers (DSCs) - 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.
The new MPLAB® Starter Kit for Digital Power (part # DM330017, $129.00), also announced today, allows customers to explore digital power conversion using Microchip's dsPIC33 "GS" architecture in popular digital power-conversion topologies. The Kit includes a buck converter and a boost converter with onboard programmable loads for each, along with an LCD display for voltage, current, temperature and fault conditions. An onboard debugger/programmer with a USB interface is included. Microchip also has a wide range of reference designs, demonstrating various digital power- conversion applications and topologies, such as the recently introduced Platinum-rated 720W AC-DC and the Enhanced Solar Microinverter reference designs. Microchip's full suite of standard development tools support the dsPIC33FJ09GS302 family, including the MPLAB® Integrated Development Environment.
All five members of the dsPIC33FJ09GS302 family are available today for sampling and volume production, starting $1.54 each, in 10,000-unit quantities. The dsPIC33FJ06GS001 and dsPIC33FJ06GS101A are offered in 18-pin SPDIP and SOIC, as well as 20-Pin SSOP packages. The dsPIC33FJ06GS102A, dsPIC33FJ06GS202A and dsPIC33FJ09GS302 are offered in 28-pin SOIC, SSOP, SPDIP and QFN, as well as 36-pin VTLA packages.
