This reference design is a complete solution for a brushless DC ceiling fan controller operating on AC power. It uses the DRV10983 24V three-phase motor driver to drive the motor through sinusoidal current and sensorless control. UCC28630 converts 90-265 VAC to 24 VDC. The MSP430G2201 Value Series processor decodes the infrared signal used for speed control. The included firmware allows easy integration of standard infrared remote controls based on the NEC transmission protocol.
Supports various Cortex-M cores, can be used wirelessly in the local area network, and can be used remotely in the external network.
I/Q modulator ADL5375 interfaces with dual-channel, 1.2 GSPS high-speed DAC AD9122
High dynamic range RF transmitter signal chain with external single frequency reference for DAC sampling clock and IQ regulator local oscillator generation
AT89C52 microcontroller is used as the core control component to design an electronic keyboard. The microcontroller is used as the main control core, and it forms the core main control module together with the keyboard speaker and other modules. The main control module is equipped with 8 buttons and a reset button.
The led-panel originated from the author's desire to use a donated roll of white LEDs to break out 48 LEDs on a compact board. Its output power should reach about 4W. It has no controller and is purely for testing a set of LEDs to see if they would be suitable for some form of lighting attached to a gooseneck.
The MAXREFDES1277 reference design enables quick evaluation of the MAX17852/53 for 48V two-Wheeler battery management applications (BMS)
CLLLC resonant DABs with bidirectional power flow capabilities and soft switching characteristics are an ideal candidate for hybrid electric vehicle/electric vehicle (HEV/EV) on-board charger and energy storage applications. This design demonstrates the use of a C2000™ MCU to control this power topology in closed voltage and closed current loop modes. The hardware and software available for this design can help you
reduce your time to market.
PMP20327 is a synchronous 4-switch buck/boost converter using the LM5175 controller and can be used as a reference design for heater element power stages in applications such as e-cigarettes. Output voltages from 1V to 10V can be selected over a current range of 20A to 45A by using a trim resistor on the FB pin with a bias voltage of 0.2V to 3.1V. This design also uses the non-synchronous boost regulator LMR62014 to provide the bias voltage for the LM5175 operating in low input voltage mode. The current mode controller has built-in LM5175 pulse-by-pulse current limiting function. This board includes enable, sync, and power-good functions. The design supports resistive heating elements with resistances ranging from 0.1Ω to 0.5Ω, thus supporting a variety of 200W operating conditions.
A hardware control circuit with TMS320F28335 as the core was designed, and experiments were conducted on the AC speed regulation SVPWM algorithm.
The STM32 Nucleo-64 board provides an affordable and flexible way for users to try out new concepts and build prototypes by choosing from the various combinations of performance and power consumption features, provided by the STM32 microcontroller.
