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.
LIS344ALH adapter board for standard DIL24 socket
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.
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).
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.
10 W Adapter for Portable Audio Players with Latching Overvoltage and Over-Temperature Shutdown Protection
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.
This application note shows a reference design using the MAX15026 low-cost, high-efficiency synchronous buck converter in an auxiliary power supply for LCD TVs or set-top boxes. This reference design generates a 5V, 5A power supply from a wide, 6.5V to 24V input voltage range.
Multi-sensor predictive maintenance kit with IO-Link stack v.1.1
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.
