The Demands of a Power Supply Controller
To amply regulate a power supply, a digital controller with advanced technologies is required. C2000™ Piccolo™ microcontrollers from Texas Instruments Inc. are primed for the job with the processing performance, actuation technology, and sensing precision to proficiently and reliably control a digital power supply:
-
C2000’s C28x™ processing core is optimized for math instructions used in a digital power control processing, allowing it to support greater performance on lower cost MCUs.
- Moreover, select Piccolo MCUs (F2803x, F2806x and F2807x) even include a secondary processing core—the CLA co-processor—allowing tasks to be partitioned and multiple power control loops to be independently operated.
- High resolution and completely configurability PWM’s empower adept actuation of even the most advanced power supply topologies.
- Rapid sensing 12-bit ADC’s allow for higher power supply operating frequencies to enable greater performance, reduced board area, and lowered costs.
C2000 MCUs in Power Converter Designs
TI’s TIDMx family of power control systems take full advantage of the C2000 microcontroller’s abilities. Three particular TI reference designs that use the controller include: a two phase interleaved power factor correction (PFC) design; a phase-shifted full bridge DC/DC design; and a resonant LLC half bridge DC/DC design.

Half-Bridge DC/DC Converter
Factor Correction Converter
Each of these designs includes a quick start guide and a GUI-based interface to quickly get the boards up and running. Further documentation and examples are also provided for further experimentation.
C2000 Power Conversion Reference Material
As with all TI reference designs; schematics, design guides and design files are included for each of these kit-based boards.
First, the controlSUITE software package includes the relevant programs for each of the boards. TI has also produced a series of power supply workshops centering on the C2000 microcontrollers. After all, there is nothing like hands-on interaction and experimentation.
The Piccolo MCU high voltage digital power supply developer’s kits will also help with the experimentation to implement your design. With the kit, you can quickly and easily make changes that suit the specific needs of each application.
Next, the digital power software library contains a series of macro-based functions and re-usable code blocks. These code blocks can be used to handle PWM, power factor correction, sine wave analysis, and debugging modules. These software tools support all of the C2000 power conversion reference designs.
Additionally, a quick search of the TI E2E Community for C2000 microcontroller digital power applications yields a trove of information and discussions. Likewise, the C2000 wiki provides information that can get engineers started with the implementation of their power designs.
Finally, if you need assistance narrowing down the best TI reference design for your equipment, then see the C2000 MCU Digital Power Selection Guide .
Needless to say, if you need to implement a power conversion design for your digital equipment, then TI has a guide that will get your product to market quickly … and without that smoky fizzle.
