Piccolo™ MCU High Voltage Digital Power Supply Developer’s Kits Cost-efficiently speed design time with kits featuring bridged and bridgeless power factor correction AC/DC, resonant LLC and phase shifted full bridge DC/DC topologies implemented with one low cost MCU The new Piccolo™-based High Voltage Digital Power Developer’s Kits from Texas Instruments bring real-time communications and control capabilities to high efficiency, high power design topologies for cost sensitive designs. Coupled with an industry leading software package, the kits represent an out-of-the-box development environment capable of supporting components and voltage levels designers encounter when working with these topologies. Each kit includes a dedicated software package pre-loaded for the specific topology supported by the kit, offering a jump-start to the evaluation environment. Also included are graphical tools allowing experimentation without loading a development environment, further reducing start up time. All four kits are supported in the controlSUITE™ software system developed for C2000™ MCUs to signifigantly reduce development time allowing designers to focus on product differentiators rather than basics. controlSUITE software includes unique,optimized libraries for the C2000 devices including building blocks and drivers for digital power supply designs. These kits also include an isolated JTAG via integrated USB interface integrated, eliminating the requirement of an external emulator, reducing development costs. The Piccolo F28027* controlCARD Key Features • High voltage kits featuring 85-240VAC inputs for AC/DC toplogies and 400VDC inputs for DC/DC topologies • Bridged and bridgeless power factor correction AC/DC architectures • Phase shifted full bridge with peak current mode control • Resonant LLC with syncronous rectification • Piccolo F28027* controlCARD based EVM • Onboard isolated JTAG eliminating the need for an external emulator • High performance TI analog devices used to complete drive stages • GUI quick-start software and controlSUITE software included with each kit is ideally suited for digital power supply designs. Running at up to 60 MHz, the Piccolo F28035 MCU features dual internal oscillators, up to 128KB of flash memory, a 12-bit 4.6MSPS ADC, high resolution ePWM outputs, and the control law accelerator (CLA). The CLA is an integrated independant, floating-point coprocessor designed to run control algorithms without any CPU involvment.
