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.
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.
The MAXREFDES1227 is a miniature 12V output isolated power supply that can deliver up to 2A load current. The design employs the MAX17596 peak-current-mode controller in discontinuous-conduction mode (DCM) flyback topology running at 125kHz. The input voltage range of MAX17596 is 4.5V to 36V; however, an extra bias winding from the transformer is used to power the controller. This allows an input operating voltage of up to 60V for this design.
The PMP5242 reference design uses the UCC28810 in a single-stage, PFC-SEPIC configuration to drive a 22W LED load. This supply can operate from an input ranging from 85VAC up to 265VAC. It is capable of driving LED strings from 156V up to 208V at a fixed current of 110mA with efficiency over 89%.

In battery-powered water meters, battery life over several years is key. One of the challenges is to continuously measure water flow information while using as little power as possible. The Scan I/F sensing peripheral integrated on the ultra-low power MSP430 microcontroller solves this problem. In the water meter design, the scan interface coupled to the LC rotation detection sensor continuously detects the rotation of the thruster while the rest of the microcontroller is in a low-power sleep mode. This reference design demonstrates how to use the scan interface to achieve ultra-low power consumption (versus the same detection method using external circuitry).
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.
The FDC2214 proximity and capacitive sensing design demonstrates how to use TI's capacitive sensing technology to sense and detect the presence of various objects. This design is a complete hardware and firmware solution. The firmware processes data from a proximity sensor and two capacitive touch buttons via the FDC2214 to determine whether an object is within the target sensing area. A dedicated colored LED lights up whenever the device detects an object in close proximity to the board or detects a button press. This design is powered by one AA battery.
