A new family of dsPIC33 ‘GS’ Digital Signal Controllers (DSCs) have been announced by Microchip. The dsPIC33 FJ09GS302 family joins the company’s existing range of dsPIC DSC devices for digital power conversion.
The new devices feature lower power consumption, which enables higher efficiency in AC-DC and DC-DC power supplies, HID and LED lighting, solar inverters and other power-conversion applications.
There are five new devices in the range that are all optimised for digital-power applications via a mix of features including integrated high-speed ADCs, a zero-wait-state signal processing core, and flexible high-resolution PWMs.
These peripherals assist smooth interoperation, enabling sub-microsecond digital control loops. Other key features of this family include on-chip analogue comparators with programmable hysteresis and rail-to-rail operation, and an on-chip PMBus addresses selection current source to reduce external components.
These devices are a good option for the lowest power dissipation of any of the company’s 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 by 5 mm footprint.
