Digital Signal Controllers (DSCs) for Switch Mode Power Supplies (SMPSs featuring 50 MIPS performances have been announced by Microchip. The devices offer a 25 percent performance increase for the company’s dsPIC33F ‘GS’ series of DSCs.
The solution includes on-chip peripherals for digital-power applications, such as an Analogue-to-Digital Converter (ADC), Pulse Width Modulation (PWM) peripheral and analogue comparators. The performance increase enables higher efficiencies in power-supply applications.
The family of devices supports applications such as induction cooking, Uninterrupted Power Supplies (UPSs), inverters, intelligent battery chargers, power factor correction, HID lighting, fluorescent lighting, LED lighting, and AC-to-DC, as well as DC-to-DC power-conversion.
The DSCs are available in 28 – to 100-pin packages, with 16 – 64K of Flash. The on-chip ADC operates at up to 4 Msps, and the PWM peripherals provide up to one nanosecond resolution, with modes supporting all power-conversion topologies.
