The TPS57140-EP device is a 42-V, 1.5-A step-down regulator with an integrated high-side MOSFET. Current-mode control provides simple external compensation and flexible component selection. A low-ripple pulse-skip mode reduces the no-load, regulated output supply current to 116 µA. Using the enable pin reduces the shutdown supply current to 1.5 µA. UVLO is internally set at 2.5 V, but can be increased using the enable pin. The slow-start pin, which is also configurable for sequencing or tracking, controls the output voltage start-up ramp. An open-drain power-good signal indicates the output is within 92% to 109% of its nominal voltage. A wide switching-frequency range allows optimization of efficiency and external component size. Frequency foldback and thermal shutdown protect the part during an overload condition. The TPS57140-EP is available in a 10-pin VSON package (DRC).

The Delfino™ TMS320F28377D-EP is a powerful 32-bit floating-point microcontroller unit (MCU) designed for advanced closed-loop control applications such asindustrial drives and servo motor control;solar inverters and converters;digital power;transportation; andpower line communications. Complete development packages for digital power and industrial drives are available as part of thepowerSUITEandDesignDRIVEinitiatives. While the Delfino product line is not new to the TMS320C2000™ portfolio, the F28377D supports a new dual-core C28x architecture that significantly boosts system performance. The integrated analog and control peripherals also let designers consolidate control architectures and eliminate multiprocessor use in high-end systems. The dual real-time control subsystems are based on TI’s 32-bit C28x floating-point CPUs, which provide 200 MHz of signal processing performance in each core. The C28x CPUs are further boosted by the new TMU accelerator, which enables fast execution of algorithms with trigonometric operations common in transforms and torque loop calculations; and the VCU accelerator, which reduces the time for complex math operations common in encoded applications. The F28377D microcontroller features two CLA real-time control coprocessors. The CLA is an independent 32-bit floating-point processor that runs at the same speed as the main CPU. The CLA responds to peripheral triggers and executes code concurrently with the main C28x CPU. This parallel processing capability can effectively double the computational performance of a real-time control system. By using the CLA to service time-critical functions, the main C28x CPU is free to perform other tasks, such as communications and diagnostics. The dual C28x+CLA architecture enables intelligent partitioning between various system tasks. For example, one C28x+CLA core can be used to track speed and position, while the other C28x+CLA core can be used to control torque and current loops. The TMS320F28377D-EP supports 1MB (512KW) of onboard flash memory with error correction code (ECC) and 204KB (102KW) of SRAM. Two 128-bit secure zones are also available on each CPU for code protection. Performance analog and control peripherals are also integrated on the F28377D MCU to further enable system consolidation. Four independent 16-bit ADCs provide precise and efficient management of multiple analog signals, which ultimately boosts system throughput. The new sigma-delta filter module (SDFM) works in conjunction with the sigma-delta modulator to enable isolated current shunt measurements. The Comparator Subsystem (CMPSS) with windowed comparators allows for protection of power stages when current limit conditions are exceeded or not met. Other analog and control peripherals include DACs, PWMs, eCAPs, eQEPs, and other peripherals. Peripherals such as EMIFs, CAN modules (ISO 11898-1/CAN 2.0B-compliant), and a new uPP interface extend the connectivity of the F28377D. The uPP interface is a new feature of the C2000™ MCUs and supports high-speed parallel connection to FPGAs or other processors with similar uPP interfaces. Lastly, a USB 2.0 port with MAC and PHY lets users easily add universal serial bus (USB) connectivity to their application.
