Programming challenges have been addressed through TI’s free controlSUITE platform that includes more than 25 modular digital power software blocks. Developers of digital power in applications such as servers, telecom rectifiers, lighting, renewable energy, as well as hybrid and electric vehicles are expected to benefit.

Each kit is based on a single C2000 Piccolo MCU with integrated high-performance analog, PWMs and other control-oriented peripherals. Software configurable tuning allows for more flexibility to adjust power stages to support multiple end-product requirements, as opposed to time-intensive redesign of system hardware.

TI says the kits include all of the hardware and software required to be up and running in 10 minutes or less. Additionally, the onboard isolated XDS100 USB JTAG emulation simplifies debugging and programming.

The High Efficiency Bridgeless PFC AC/DC Developer’s Kit features robust hardware and software, to enable designers to increase overall system efficiency with higher power factor and lower total harmonic distortion through flexible, digital control of an AC Rectifier stage. It is configurable for adaptive current control and non-linear voltage control loop modes, as well as output over-voltage protection and inrush current limiting. Auto-ranging AC input supports voltages from 100VAC to 220VAC and outputs 380 to 400VDC up to 300 Watts.

The Phase Shifted Isolated Full Bridge DC/DC Developer’s Kit supports Peak Current Mode Control with on-chip slope compensation, allowing designers to jump start Isolated DC/DC power supply designs without additional external circuitry. Peak Efficiencies of up to 95percent, with 90+ percent efficiency from 10 to 90 percent of rated power can be realised, while there is also support for input voltages from 380 to 400VDC with a regulated 12VDC output capable of supporting up to 600 Watts.

The Resonant LLC Isolated Half Bridge DC/DC Developer’s Kit provides complete hardware and software to allow designers to quickly evaluate a digitally controlled isolated DC/DC power supply. Input range supports 380-400VDC with a regulated output of 12VDC, supporting up to 300 Watts at a peak efficiency of 93.7%.

TI’s C2000 MCU digital power portfolio also includes additional kits, such as the High Voltage PFC AC/DC Developer’s Kit that provides complete hardware and software for two phase interleaved power factor correction.  Free on-demand digital power training is available online, and third-party Biricha Digital Power Ltd. offers an in-depth training designed to give developers with all experience levels a solid foundation of digital power theory and extensive hands-on labs.
