The new STPS50U100C is a rectifier diode and can be used in the output of power supplies for adapters, desktop PCs, servers, TV and video products, communication equipment, and many other electrical appliances. It is the first member of a new family of ultra-low forward voltage (ULVF) Schottky rectifier diodes from ST, which will provide a range of diode properties to fulfill various applications. The forward voltage drop is the main source of power losses in power Schottky diodes used for secondary rectification, therefore minimizing this voltage drop is a key innovation driver. Featuring an ultralow forward voltage drop, this device, packaged in TO-220AB and I²PAK, is intended to be used in notebook, game station and desktop adaptors as well as server SMPS. It has been especially designed to help power supply manufacturers meet the recently introduced worldwide efficiency standards...

The LM25066 provides designers of blade servers, storage networking systems, routers/switches and modular subsystems with a solution that improves system reliability and reduces operating expenses in data centers. National’s LM25066 integrates high-performance monitoring, protection and control blocks that precisely control and manage the electrical operating conditions of each blade in the chassis. It also provides accurate monitoring of critical system power consumption and fault conditions. The LM25066 continuously supplies the system management host with real-time power, voltage, current, temperature and fault data for each blade subsystem. The LM25066’s system management bus (SMBus) communications interface delivers this data using the PMBus protocol. The host’s system diagnostic and optimization routines use the data to increase system reliability and minimize the data center’s total power consumption...

Primary side regulation (PSR) PWM controllers offers designers of mobile chargers, adapters and LED lighting applications multiple solutions to meet the stringent power and regulatory specifications such as ENERGY STAR; Level V. The devices simplify designs, save board space and meet today’s demands for power savings. Key features available are 30mW standby power, HV start up and an integrated power MOSFET for ease of design, primary side regulation without secondary side feedback and a universal AC input range. Fairchild’s PSR PWM controllers achieve constant voltage (CV) (±5%), constant current (CC) (±7%), 30mW standby power and ENERGY STAR Level V efficiency, all with a competitive bill of materials (BOM) cost and component count. PSR PWM controllers achieve the most accurate CC through built-in, proprietary TRUECURRENT technology and tight CV without secondary-side feedback circuitry. Constant current allows the device to accommodate different numbers of LED units in a string, increasing design flexibility, stretching the lifetime of HB LEDs and reducing time-to-market. PSR PWM controller portfolio, including the FSEZ1307, FSEZ1317 and FAN103, enhance Fairchild’s extensive power offerings that enable efficient electronics and maximize energy savings in power-sensitive applications such as power adapters, power supplies, lighting applications, computers, industrial controls and home appliances...

Additional new features of the STM32 XL-density devices include additional high-speed volatile memory (RAM), up to 96KB, which can simplify software design and speed-up execution. Six more timers are also included, increasing flexibility for applications such as motor control, factory automation or power distribution. Furthermore, a Memory Protection Unit (MPU) has been added, which is transparent to existing software but allows new applications to protect specific code or data during execution. This feature permits efficient use of existing certified software modules in projects such as medical or metering equipment, saving the time and cost to re-certify the complete application. The 1MB Flash memory is organized in two banks of 512Kbytes.This dual-bank architecture thereby enables safe upgrading of applications in the field by uploading new software into the second memory bank. The update can then be copied across safely into the main bank, and the process managed to protect against hazards such as power loss while the upgrade is being applied. The new devices complement the existing product lines of the industry’s most extensive Cortex-M3 microcontroller portfolio. The STM32F101Access Line XL density devices continue to provide the low-cost and high-functionality established with the original STM32 Access Line. The STM32F103Performance Line XL density devices extend the existing Performance Line that features faster 72MHz core and extra connectivity like USB and CAN, to applications that require additional memory. With these XL density devices, both lines now comprise versions with 768Kbyte or 1Mbyte Flash memory in a choice of 64-, 100-, or 144-pin packages...
