Microchip dsPIC33FJ09GS302 DSCs

Microchip Technology has released the dsPIC33 GS family of digital signal controllers (DSCs). The DSCs offer new features while lowering power consumption, enabling higher efficiency in AC-DC and DC-DC power supplies, HID and LED lighting, solar inverters and other power conversion applications.

The five-member dsPIC33FJ09GS302 family is optimised 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 submicrosecond digital control loops.

Other 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. The 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 smaller 36-pin VTLA package, which has a 5 x 5 mm footprint.

The MPLAB Starter Kit for Digital Power (part # DM330017) allows users 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 for voltage, current, temperature and fault conditions. An onboard debugger/programmer with a USB interface is included.

Microchip’s full suite of standard development tools supports the dsPIC33FJ09GS302 family, including the MPLAB integrated development environment.
