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%.
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 evaluation board supports the MC33810EK automotive engine control IC for injectors, solenoids, lights, and relays.
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).
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.

The MAXREFDES1214 is a portable USB charger that uses a lithium-ion (Li+) battery to charge a USB device from a USB Standard-A connector.
The MAX17504 high-efficiency, high-voltage, synchronously rectified step-down converter with dual integrated MOSFETs operates over a 4.5V to 60V input. The converter can deliver up to 3.5A and generates output voltage from 0.9V to 90% VIN. Built -in compensation across the output voltage range eliminates the need for external components. The feedback (FB) regulation is accurate to within ±1.1% over -40°C to +125°C. The devices are available in a compact (5mm x 5mm ) TQFN lead (Pb)- free package with an exposed pad. Simulation models are available. The MAX17504 features a peak-current-mode control architecture with a MODE feature that can be used to operate the device in pulse-width modulation (PWM) , pulse-frequency modulation (PFM), or discontinuous mode (DCM) control schemes.
When it is necessary to plug in a board into a system that is currently powered, it is critical to control the inrush current to prevent damage/system fault conditions. This application provides a simple circuit to achieve this function as well as an easy method for resetting the system and monitoring against temperature issues.
This TI verified design provides principles, component selection, TINA-TI simulation, verification and measurement performance, Altium schematic, PCB layout for automotive battery pack monitoring applications. This design uses the automotive AEC-Q100 qualified 12-bit, 4-channel, 1Msps SAR ADC ADS7950-Q1 and isolated system hardware. This isolated input design with four-wire shunt resistors is ideal for such applications using high and low voltage automotive battery packs. It can be used to monitor battery pack current (from -5A to +5A) and extremely high voltages (up to 750V). TINA simulations on input and reference drivers validate design solutions and component selections, while measured results prove the performance of precision designs.
