REF_ICL8810_LED_43W_BM This 43 W reference design uses Infineon's high power factor flyback controller ICL8810. The evaluation board is a constant voltage (CV) secondary side regulation (SSR) system designed for use with a constant current (CC) converter for LED lighting applications. Two-stage topologies are becoming increasingly popular due to the easy scalability of primary-side power and secondary-side characteristics. The REF_ICL8810_LED_43W_BM solution features a plug-and-play design and can be used with the secondary-side DC/DC evaluation board. As a default, the reference design board is equipped with a depletion mode MOSFET BSS126I based startup circuit on a small adapter board. This setup will significantly reduce standby losses. If low standby power consumption is not required, the startup circuit can be changed to a resistive startup design. This reference design comes with two conditioning circuits. Both are plug-and-play solutions, but at least one circuit must be connected to the motherboard. There is a cost trade-off between the two evaluation boards; the TL431 evaluation board is lower cost and has good standby performance, while the op amp board exhibits excellent overall performance at the 30 mW power level. With its benchmark power factor correction and total harmonic distortion performance at full and light load conditions, the ICL8800 supports window driver and platform designs. In addition, the IC combines excellent efficiency with low EMI characteristics without compromising light quality.
The ASL5015EVBMST is the main evaluation board for NXP's Matrix LED Controller (MLC) ASL5015SHN, which enables evaluation of external lighting systems.
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).

10 W Adapter for Portable Audio Players with Latching Overvoltage and Over-Temperature Shutdown Protection
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.
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.
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.
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.
The MAX17574, high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs operates over a 4.5V to 60V input. The converter can deliver up to 3A current.
