New Family of dsPIC33 “GS” Digital Signal Controllers Enable Full Digital Control for Cost-Sensitive Power-Conversion Applications
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 5×5 mm footprint.
Development Support
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.
Pricing & Availability
All five members of the dsPIC33FJ09GS302 family are available today for sampling and volume production, starting $1.54 each, in 10,000-unit quantities.
