Demonstration board using STM32F100 to realize full 3.3V ACS/Triac control
This reference design implements a reinforced isolated three-phase inverter subsystem using isolated IGBT gate drivers and isolated current/voltage sensors. This design uses the AMC1306E25 delta-sigma modulator for accurate shunt-based inline motor phase current sensing. The modulator output is Manchester encoded, simplifying clock and data signal routing between the MCU and the modulator. The modulator's high CMTI helps suppress inverter switching noise transients from causing data corruption on the controller side. A compact solution is achieved using a small size modulator. TIDA-00914 provides an interface to an external MCU or FPGA so that a SINC digital filter can be used to demodulate the AMC1306E25 output bit stream. This reference design uses the F28379D Delfino control card, which is connected to the card described in the reference design via an adapter card for current sensing using SINC filters.
The MAX17690 is a peak current mode, fixed-frequency switching controller specifically designed for the isolated flyback topology operating in Discontinuous Conduction Mode (DCM). The device senses the isolated output voltage directly from the primary-side flyback waveform during the off-time of the primary switch.
The MAX668/MAX669 constant-frequency, pulse-width modulating (PWM), current-mode DC-DC controllers are designed for a wide range of DC-DC conversion applications, including step-up, SEPIC, flyback, and isolated-output configurations .
65 W isolated flyback power supply using InnoSwitch3-EP PowiGaN (INN3679C-H606) and MinE-CAP (MIN1072M)
This reference design helps designers develop a cost optimized ultrasonic water-metering subsystem using an integrated, ultrasonic sensing solution (USS) module, which provides superior metrology performance with low-power consumption and maximum integration. The design is based on the 64KB MSP430FR6043 microcontroller (MCU), with integrated high-speed, ADC-based, signal acquisition and an integrated low energy accelerator (LEA) to optimize digital signal processing.
The PMP10110 is designed to convert universal input AC voltage to an isolated 17V...30V@6A, suitable for charging lead-acid and lithium-ion batteries. The converter is a constant voltage and constant current generator, the set points for output voltage (charge level) and current can be set via two PWM signals. The first stage is the PFC boost stage, while isolation and current stabilization are performed by the DC-DC half-bridge stage. The isolated quasi-resonant flyback converter provides all internal voltages and some additional current to the external load (fan or analog section), specifically 12V@400mA and 5V@300mA.
Freedom FRDM-KL82Z is a development board for Kinetis ultra-low power KL82 72Mhz 32-bit Arm ® Cortex ® -M0+ MCU.
The ESC module is a very important subsystem in non-military UAVs. Users need more efficient models to achieve longer flight times, better dynamic behavior and smoother and more stable performance. The design uses an electronic speed controller (ESC) commonly used in unmanned aerial vehicles (UAVs) or drones.
Speed control is done sensorless and the motor was tested using FOC speed control up to 1.2kHz electrical frequency (12kRPM, 6 pole pair motor). Our drone ESC high-speed sensorless FOC reference design features a best-in-class FOC algorithm implementation that enables longer flight times, better dynamic performance, and higher integration resulting in smaller board size and BOM components less. Sensorless high-speed FOC control uses TI's FAST™ software observer, leveraging the InstaSPIN-Motion™ C2000™ LaunchPad and DRV8305 BoosterPack.
The TWS headset charging bin solution developed based on ML51 mainly has two major functions: data communication with the headset and charge and discharge management. Data communication is carried out with the headset through the pogo pin to realize pop-up windows and other functions that require data communication; the battery charging management unit has built-in lithium battery overcharge, over-discharge, short circuit, over-current and other protection functions, making the system stable and reliable.
This kit permits to evaluate the NHS3152 chip and to start the development of a specific use case.
This 50V/1A boost converter is designed to operate from a nominal 12V input voltage, but will operate in the automotive range of 5V - 40V. This design is low cost and requires only an area of 50mm x 50mm.
The KITPF8101FRDMEVM and KITPF8201FRDMEVM evaluation boards feature the PF8101/PF8201 energy management integrated circuit for high-performance processing applications
