This reference design utilizes an isolated modulator and independent digital filter to implement a Class 0.5 three-phase power measurement system with an isolated shunt sensor, eliminating the need for an integrated synchronization filter and allowing an optional host microcontroller (MCU). ) will be broader in scope. In this design, the current sensed by the isolated modulator and the phase voltage sensed by the host microcontroller are synchronized; more advanced metering algorithms are supported using the Simplelink™ ARM Cortex M4 host MCU. This design protects against magnetic tampering attacks by using current sensors and a power supply that does not use any transformers or other magnetic components. This subsystem design has been tested and includes hardware.
Implement precision electronic scale design using the 24-bit Σ-Δ ADC AD7195 with built-in PGA and AC excitation
The PMP11769 reference design is a comprehensive solution for 700W automotive audio amplifiers. This boost converter provides a 36.0V, 10.0A continuous/20.0A peak output from an input voltage of 9 to 16V. It contains two Class D amplifiers delivering 2 x 175W (loaded into 4 ohms, left and right channels) and 1 x 350W (loaded into 2 ohms, subwoofer) power.
This reference design demonstrates an interface implementation to multiple high-voltage bipolar input, 8-channel, multiplexed input SAR ADCs (6) via a Sitara Arm processor using a Programmable Real-Time Unit (PRU- ICSS) expands the number of input channels. The ADCs can be configured so that the same channels can be sampled simultaneously across all ADCs. This design highlights the PRU-ICSS's ability to handle a data rate of 1536ksps (each sample = 16 bits) (640 samples sampled per line cycle). For a 50Hz period, this equates to 32ksps per channel between 6 ADCs simultaneously (640 samples/period*50Hz*6 ADC*8 channels = 1536ksps). In addition, a second PRU is used to post-process the data to achieve coherent sampling.
This reference design for a 6A step-down LED driver is based on the MAX16821 device. This circuit drives a single LED. This design includes the circuit specifications, circuit schematic, and circuit description and performance.
This fully tested, USB power delivery reference design is a high efficiency, high power density, AC/DC adapter solution with a wide input voltage range (85 - 265VAC) for laptop adapters and smartphone charger applications. It adopts active-clamp-flyback topology controlled by TI’s newest ACF controller UCC28780 as the mainly power supply stage. This design uses TPS25740B, TI’s PD source controller, to achieve a full PD 2.0 function. The design achieves a peak efficiency of 94% at a very high switching frequency. The design’s power density is increased to 30 W/in3, which is much higher than traditional solutions.
This is a very simple open source scanning laser rangefinder. It uses triangulation. Its components cost less than $35 (excluding shipping). This lidar is very useful in robotics - for SLAM and navigation tasks.
