This reference design uses multiple microphones, a beamforming algorithm, and other processes to extract clear speech and audio amidst noise and other clutter. The rapid increase in applications that are used in noise-prone environments for voice activated digital assitants creates demand for systems that extract clear voice from noisy environments. The reference design uses a microphone array and a sophisticated signal processing to extract clear audio from noisy environments.
This EVK supports NXPMC33812. MC33812 is an engine control analog power IC suitable for motorcycle and single/double cylinder small engine control applications.
The MAXREFDES1174 is centered around the MAX17501 ultra small, high-efficiency, high-voltage, synchronous stepdown DC-DC converter with integrated MOSFETs. This design provides a -24V output and up to 150mA of load current with an input voltage range of 22V to 30V. Unlike a traditional design, this reference design is configured to work in a buck-boost topology to produce negative output voltage from positive input voltage.
The PMP10581 reference design provides all the power rails required to power Altera's Cyclone® IV E FPGA. The DE2-115 was developed by Terasic and you can purchase this board through the Terasic website.
To meet energy efficiency requirements, ceiling fans and ventilation fans will move from simple AC induction motors to brushless DC motors (BLDC). BLDC motors require AC-DC conversion with high efficiency and high power factor when operating on AC power. It also requires the use of highly efficient controlled inverters for low-noise operation. Reference design TIDA-00652 uses a single-stage power supply to convert an AC power input to a low-voltage DC output, helping meet the challenges of higher efficiency and power factor in a simpler way. It also incorporates a fully integrated and properly protected single-chip sensorless sinusoidal brushless motor controller for low-noise operation.
The MAX17596 is a peak-current-mode controller for designing wide input-voltage flyback regulators. The device offers input thresholds suitable for low-voltage DC-DC applications (4.5V to 36V) and contains a built-in gate driver for an external n-channel MOSFET.
The MAXREFDES01261 is a reference design for the asset tracker application based on the Maxim® solution. This reference design is a power management platform for the asset tracker, which includes the MAX32660, MAX77840, MAX77640, and MAX77827. This design demonstrates a small-size, low-power, highly effective, highly accurate, and flexible power management system.
Power over Ethernet (PoE) is a technology that allows network cables to deliver power to a powered device (PD) via power-sourcing equipment (PSE) or midspan and has many advantages over traditional methods of power delivering. The MAXREFDES1148 reference design is a 36V~57V input to 5V/2.5A output flyback PoE PD power module to be used in Ethernet equipment that needs the 5V power supply to be isolated from the primary Ethernet power.
Designers who must interface 1-Wire® temperature sensors with Xilinx field-programmable gate arrays (FPGAs) can use this reference design to drive a DS28EA00 1-Wire slave device. The downloadable software mentioned in this document can also be used as a starting point to connect other 1-Wire slave devices. The system implements a 1-Wire master connected to a UART and outputs temperature to a PC from the DS28EA00 temperature sensor. In addition, high/low alarm outputs are displayed from the DS28EA00 PIO pins using LEDs.
The complete PMBus power system can power 3 ASIC/FPGA cores, DDR3 core memory, and provide auxiliary voltage for high-performance Ethernet switches.
