The LTC3633 is a high efficiency, 4MHz synchronous dual output buck regulator that incorporates a unique constant frequency/controlled on-time, current mode architecture. It can deliver up to 3A of continuous output current from each channel at output voltages as low as 0.6V from a 4mm x 5mm QFN package. The LTC3633 operates from an input voltage of 3.6V to 15V, making it ideal for dual-cell Li-Ion applications as well as 5V and 12V intermediate ...

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.

Vishay released three new dual single pole double throw (SPDT) and dual double pole double throw (DPDT) CMOS low-voltage analog switches. The devices combine low-voltage operation and low on-resistance in small miniQFN packages for audio, SIM card, and multi-purpose signal switching in space-constrained portable end products.

National Semiconductor has introduced what it says is the industry’s smallest 4 MHz synchronous step-down DC-DC converter that provides up to a 1A output current over an input voltage range of 2.3V to 5.5V. The LM3691 DC-DC converter is optimized for powering high-performance processors from a single Li-Ion cell battery in mobile phones, personal media players and other mobile devices. A member of National’s PowerWise® energy-efficient produ...

Semtech's SC4501, SC4502 and SC4502H are current-mode, adjustable frequency step-up (boost) converters with an internal 2A, 40V switch.

Atmel today announced that its battery management circuit ATA6870 is the industry's first solution that features active cell balancing with capacitors or inductors for high-cell-count Li-Ion batteries supporting supply voltages up to several hundreds volts such as used in electrical/hybrid vehicles, e-bikes or uninterruptible power supplies.

Built by Orbital Sciences Corporation and powered by Saft’s proven lithium-ion (Li-ion) technology, the MEASAT-3a successfully launched into space on Monday, 22 June 2009 from a Land Launch rocket at the Baikonur Cosmodrome, Kazakhstan launch site. The MEASAT-3a contained two of Saft’s VES 140 batteries on-board, for a total of 72 VES 140 cells. This launch makes a total of 33 spacecraft in orbit today using Saft Li-ion battery technology.

Saft has been selected by AR-SAT SA to supply the lithiumion (Li-ion) battery system that will power ARSAT-1, the first communications satellite to be designed and integrated in Argentina. Arsat-1,the first in a series of satellites, is scheduled to be launched in 2012 and will provide coverage for Latin America.
