The KITPF8200FRDMPGM is a programming board with a 56-pin QFN socket that is compatible with all PF8100/PF8200 series devices. This kit integrates all the hardware required to program the OTP registers in the PMIC.
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 .
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 MAXREFDES1275 has three main blocks: the microcontroller, ADC/DAC IC MAX11311, and three LED drivers.
The KITPF8101FRDMEVM and KITPF8201FRDMEVM evaluation boards feature the PF8101/PF8201 energy management integrated circuit for high-performance processing applications
65 W isolated flyback power supply using InnoSwitch3-EP PowiGaN (INN3679C-H606) and MinE-CAP (MIN1072M)
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.
Replacing halogen lamps with LEDs in MR16 light fixtures can save substantial energy while reducing electricity and maintenance costs. This application note details the advantages of using LEDs in MR16 fixtures, and it presents an LED driver circuit that enables a 5W white LED with integrated heatsink to replace a 10W halogen bulb in MR16 lamps.
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.
This is a reference design for an LED display-backlight driver. The design uses a boost power supply with adaptive feedback for efficiency and linear current sinks for a high dimming ratio (2000:1). The input voltage is 8V to 18V with 50V transients, and the load is three parallel strings of 8 LEDs (34V) at 150mA/string. The MAX16809 16-channel LED driver is featured.
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.
New, completely wireless earbuds are charged by the battery inside their carrying case—a unique design that requires small solution sizes and efficient power components. Additionally, the large demands in this market are increasing the need to deliver equivalent functionality more economically. This ultra-low power reference design exhibits a charging case battery and boost converter powered from USB input.
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.
This application note provides a reference design for an IEEE® 802.3af-compliant, 12.95W adjustable-output powered-device module. Assembled on a 12cm² PCB, the module is based on the MAX5941B PWM controller and includes hot-swap power switching, a DC-DC converter, and a pair of ORing diode bridges for compatibility with an external 12V adapter.
