This reference design is built to enable multiple room comfort control in connected HVAC systems. Sensing temperature, humidity, and pressure allows independent monitoring and air-flow adjustment in each zone. This TI Design converts a constant air volume (CAV) into a variable air volume (VAV) system. Collected data can be transmitted wirelessly to the smart thermostat or gateway. Onboard sensors can be employed to allow predictive maintenance, shorten technical troubleshooting time, and reduce overall energy consumption. Long battery life allows the smart damper to run for many years without the need to spend time and money on battery replacement.

The MAXREFDES1123 is a compact boost power-supply design for high-voltage applications with low current requirements where extremely low cost and small size are top priorities.
Power over Ethernet (PoE) is a technology that allows network cables to deliver power to a powered device (PD) through power-sourcing equipment (PSE) or midspan, and has many advantages over traditional methods of delivering power.
The MAXREDES1126 provides the internal core voltage (VCCINT) for Xilinx Ultrascale+ FPGAs.
Supercapacitors are increasingly being used in a number of applications in electric vehicles, transportation equipment, industrial machinery and utility grids. In the MAXREFDES1215, a supercapacitor-based energy harvester is demonstrated using the MAX17220. The circuit uses a supercapacitor to provide backup energy. The first stage of the circuit charges a supercapacitor, and the second stage of the circuit regulates the voltage from the supercapacitor to supply various sensors with a steady output voltage. In this system, the MAX17220 is used for regulating the output voltage from the supercapacitor.
Due to its simplicity and low cost, the flyback converter is the preferred choice for low-to-medium isolated DC-DC power-conversion applications. However, the use of an optocoupler or an auxiliary winding on the flyback transformer for voltage feedback across the isolation barrier increases the number of components and design complexity. The MAX17690 eliminates the need for an optocoupler or auxiliary transformer winding and achieves ±5% output voltage regulation over line, load, and temperature variations.
The 15-watt single-coil fixed-frequency wireless charging transmitter reference design features the WCT10xx transmit controller IC and integrates all the features required for a Wireless Power Consortium (WPC) Qi-compliant wireless power transmitter design.
The TIDA-00786 is a small size brushed DC motor controller with fixed 100% duty cycle speed input and variable current regulation. The DRV8871's integrated current sensing capability enables the design to utilize standard potentiometers, allowing the user to quickly change current limit levels in motors powered by 12 to 24V inputs.
The TIDEP0066 reference design uses TI's Embedded Speech Recognition (TIesr) library to highlight the speech recognition capabilities of the C5535 and C5545 DSP devices; and based on successful keyword collection, indicates how to run speech to print pre-programmed keywords on the C5535eZdsp OLED screen Trigger example. This design also describes the steps to customize trigger words.

This development platform targets Ethernet/IP slave device communications, enabling designers to implement the Ethernet/IP communications standard in multiple industrial automation devices. It enables low-footprint designs with minimal external components and best-in-class low-power performance.
Maxim's Power Amplifier Biasing (MAXREFDES39#) features a PA Bias circuit with the flexible Programmable Mixed Signal I/O (PIXI™) product, the MAX11300. The 2-stage amplifier design biases a 15W, LDMOS PA implemented with unprecedented simplicity, and is capable of biasing many existing PAs. Design files are available and boards are available for purchase.
This application note presents a reference design for a nonisolated LED driver intended to operate directly from a 400V DC input. The design drives a string of 27 WLEDs (white LEDs) or, optionally, 6 amber LEDs at 400mA. The topology is a discontinuous flyback with a transformer. The MAX16801 HB (high brightness) LED controller is featured.
The FRDM-HB2001-EVM evaluation kit allows users to practice using all features of the MC33HB2001 H-bridge device with FRDM-KL25z and SPIGen software.
