Microchip announces new family of dsPIC DSCs

Microchip has expanded its dsPIC digital signal controller (DSC) portfolio with a new family of devices designed to enable full digital control for cost sensitive power conversion applications.

The dsPIC33FJ09GS302 family is said to offer new features while lowering power consumption, enabling higher efficiency in ac/dc and dc/dc power supplies, HID and led lighting, and solar inverters. The five devices in the family are optimised with 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. Microchip says other key features include on chip analogue comparators with programmable hysteresis and rail to rail operation, and an on chip PMBus address selection current source to reduce external components. The new DSCs are said to offer the lowest power dissipation of any of the GS family members and are the first available in a 20pin SSOP package and the smaller 36pin VTLA package, which has a 5x5mm footprint.
