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.
