TI adds new MCU kits for digital power supply design

Texas Instruments has announced three new microcontroller development kits based on its TMS320C2000 microcontroller (MCU) family. The new kits are designed for designing complex digital power supplies with features such as bridgeless design and Peak Current Mode Control (PCMC) with Slope Compensation. TI is offering free controlSUITE platform that includes more than 25 modular digital power software blocks. The application power supply designers can design using these kits includes servers, telecom rectifiers, lighting, renewable energy, as well as hybrid and electric vehicles.

Each kit is based on a single C2000 Piccolo MCU. Software configurable tuning feature in these kits 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 key features:

1. High Efficiency Bridgeless PFC AC/DC Developer's Kit:

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

2. Phase Shifted Isolated Full Bridge DC/DC Developer's Kit:

Peak Efficiencies of up to 95 percent, with 90+ percent efficiency from 10 to 90 percent of rated power
Support for input voltages from 380 to 400VDC with a regulated 12VDC output capable of supporting up to 600 Watts.

3. Resonant LLC Isolated Half Bridge DC/DC Developer's Kit:
Input range supporting 380-400VDC with a regulated output of 12VDC, supporting up to 300 Watts at a peak efficiency of 93.7 percent

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.
