Linear Technology has introduced the LTC3872, a current mode step-up DC/DC controller with 550kHz operating frequency. The LTC3872 does not require a sense resistor, saving board space and improving efficiency. This is a compact solution for converting a 2.5V to 9.8V input voltage up to a high output voltage. VOUT as high as 60V is achievable without a sense resistor, and when a sense resistor is used, the output voltage is limited only by extern...

Excelsys Technologies has introduced powerKit, a simple to use 1U modular power supply development kit. Part of the highly acclaimed Xgen series of multi-output, high power density power supply family, powerKit allows system design engineers to configure exactly the prototype power supply their application requires without lengthy design cycles and manufacturers prototype development or non-recurring engineering charges.

Linear Technology has introduced the LTC4101, a fast, precision smart battery charger controller that operates with or without a host microcontroller. The IC is 100% compliant with Rev. 1.1 SMBus specifications and meets the requirements of Smart Battery System (SBS) Level 2 charging functions. It is optimized for 3V to 5.5V charging voltages, suitable for 1-cell Li-Ion and 3- to 4-cell nickel-chemistry batteries.

SynQor has extended its range of sixteenth brick dc/dc converters by now offering isolated outputs of 5V/12A and 1.8V/25A, with up to 60W of usable power in a 1.17in2 footprint. Using the DOSA standard pinout and footprint, the sixteenth brick footprint uses 43% less board space than eighth brick converters.

Vicor has announced the availability of a range of 52 Factorized Power Architecture (FPA) Customer Evaluation and Validation Boards, featuring BCM, PRM and VTM V•I Chip power components. In addition Vicor has created an expanding library of V•I Chip application notes to support the implementation of power system designs. The introduction of the evaluation boards and application note library provides a quick and easy way to get an appreciati...

Linear Technology has introduced the LTC4080, a multi-function IC featuring a standalone linear battery charger and a highly-efficient synchronous buck converter. The USB-compatible battery charger can charge a single-cell Li-Ion battery up to 500mA without overheating the device or surrounding components. The 300mA buck converter features selectable mode operation and synchronous rectification to achieve efficiencies up to 96%.

TDI is introducing a complete series of environmentally sealed power modules (ESPM). The first modules to be released are the efficient and ruggedized 1000 and 2700W units. These modules are designed to withstand and operate reliably in harsh environments and critical applications. The ESPM series is also electrically hardened to survive severe AC input transients.

Transistor Devices' Dynaload Division has announced the addition of Ethernet communication capabilities to its popular RBL, MCL and WCL series of programmable electronic loads.

Transistor Devices (TDI) has introduced its Signature 1000W, 1U Power Module providing -54VDC for Rectifier applications and +48VDC for Front End architectures. The modules are designed for use in 300mm or mid-plane cabinets by featuring a chassis depth of just 10.63in. They fit three-across in the matching 19in , 1RU power shelf and share up to 3000W per shelf.

New from Lincoln-based VxI Power is the Studer Compact series of inverter/chargers, which combine the functions of a sine-wave inverter, a battery charger and an automatic transfer system to manage the available power. Designed to provide reliable and silent operation, the inverter/charger connects to an AC mains supply or generator and a 12V, 24V or 48V battery.
