With this design, users of the OV788 ultra-low-power video compression chip can easily implement real-time streaming of audio and video data over Wi-Fi®. It demonstrates a single-chip implementation on the SimpleLink™ CC3200 Wi-Fi wireless microcontroller that supports RTP video streaming and Wi-Fi connectivity via 802.11 b/g/n from any smartphone, tablet or computer on the local network network for data transmission. This design implementation takes advantage of the CC3200 Internet-on-a-chip™ solution's ease of debugging to Wi-Fi networks and advanced low-power modes, making it ideal for a variety of Internet of Things (IoT) applications, such as battery-powered in smart homes. Intrusion cameras, door locks, video doorbells and 360 multi-camera.
The MAXREFDES48# reference design is a high-efficiency, high-precision, isolated DC-DC forward converter with an active clamp, current-mode PWM controller. The converter accepts 18V to 36V DC input and delivers output current up to 3.5A at 12V . Test results and hardware files provide complete documentation for the design. The board is also available for purchase.
TIDA-00827 is an integrated sensor-based BLDC motor controller reference design for low-power, battery-powered brushless DC motor applications. The 8 to 35V operating voltage range supports 3S to 6S lithium polymer battery power supplies. Specific applications include camera heads, low-power fans and robots. The motor controller consists of the MSP430G2353 16-bit, ultra-low power microcontroller and the DRV8313 highly integrated 2.5A triple half-bridge driver. The MSP430G2353 utilizes Hall sensor-based communication feedback to provide the correct drive voltage to the motor through the DRV8313. Onboard potentiometers and buttons provide a simple interface to control the motor.
The PMP10733 uses the LM5160 in a Fly-Buck-Boost topology with the primary side set to a negative voltage. Setting the primary side to a negative voltage reduces the turns ratio of the transformer and therefore allows for better line and load regulation. The primary and secondary voltages are set to negative 15V and positive 15V respectively. The maximum operating current on the primary and secondary voltage rails is set to 150mA. The switching frequency is set to 200kHz.
The MAX17506 high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated high-side MOSFET operates over a 4.5V to 60V input. The converter can deliver up to 5A and generates output voltages from 0.9V up to 0.9 x VIN. The feedback (FB) voltage is accurate to within ±1.4% over -40°C to +125°C. The MAX17506 uses peak current-mode control and can be operated in the pulse-width modulation (PWM), pulse-frequency modulation (PFM), and discontinuous conduction mode (DCM) control schemes.
The TIDA-00792 TI Design provides monitoring, balancing, primary protection and gauging for a 12 to 15 cell lithium-ion or lithium-iron phosphate based batteries. This board is intended to be mounted in an enclosure for industrial systems. The reference design subsystem provides battery protection and gauging configuration with parameters avoiding code development and provides high side protection switching to allow simple PACK- referenced SMBus communication for battery status even while protected.
This reference design functions from a base of silicon carbide (SiC) MOSFETs that are driven by a C2000 microcontroller (MCU) with SiC-isolated gate drivers. The design implements three-phase interleaving and operates in continuous conduction mode (CCM) to achieve a 98.46% efficiency at a 240-V input voltage and 6.6-kW full power. The C2000 controller enables phase shedding and adaptive dead-time control to improve the power factor at light load. The gate driver board (see TIDA-01605) is capable of delivering a 4-A source and 6-A sink peak current. The gate driver board implements a reinforced isolation and can withstand more than 100-V/ns common-mode transient immunity (CMTI). The gate driver board also contains the two-level turnoff circuit, which protects the MOSFET from voltage overshoot during the short-circuit scenario.
Texas Instruments' ZLLRC reference design enables simple and direct control of lights connected to a ZigBee Light Link network. It is designed to control a subgroup of lights on that network, such as the lights in a room in your home. It creates its own group containing lights that have touch connections to it. These lights can be added/removed later. It has 14 buttons to control status (on/off), hue, saturation, level, target selection and scene. ZLLRC is supported by Z-Stack Lighting version 1.0.2 and higher. It is based on the CC2530 system-on-chip (SoC) with integrated ZigBee radio. It connects to the onboard PIFA PCB antenna through an integrated balun. To extend battery life, the TPS62730 DCDC converter can be used to convert the CR2025 battery voltage to 2.1 V.
Ultra-low-cost EVB for MPC5744P. Evaluate the MPC5744P for functional safety and chassis-oriented automotive and industrial applications.
Since my four-wheel drive robot is powered by a 16.5V lithium battery, and there is no charger for this battery on the market, I am very confused about charging it. In desperation, we designed a portable and simple lithium battery charger. Solve the trouble of charging. The charger can output an adjustable charging current of 100mA-1A. The input voltage is VIN>18V, and it can be charged with the 19V voltage on the laptop. Charging time is generally determined according to the size of the charging output current.
The MAXREFDES1206 is a Power over Ethernet (PoE) powered device and active clamp forward converter that delivers up to 1A at 24V from a 39V to 57V supply voltage.
