Ultralow Power 15mA Synchronous Low Noise Step-Down Switching Regulator
Linear Technology has announced the LTC3620, a high efficiency, synchronous buck regulator which can deliver up to 15mA from a very small footprint for single Li-Ion-powered applications. The internal synchronous switches deliver efficiencies as high as 95% while Burst Mode® operation requires only 18uA of quiescent current, maximizing battery run time. The LTC3620 can take a 2.9V-5.5V input, and is adjustable to outputs as low as the 0.6V, wher...
Vishay's New 600-V, 8-A PFC Rectifier Series Features Diodes With Voltage Drop as Low as 1 V and Recovery Charge as Low as 62 nC in 175 °C-Rated Package
Vishay Intertechnology (NYSE: VSH) today introduced six new FRED Pt hyperfast rectifiers for consumer electronics applications. The new 600-V, 8-A devices feature an ultra-low typical voltage drop of 1 V at rated current, fast recovery times as low as 16 ns in hard switching conditions, and typical leakage current at 125 °C as low as 30 µA.

DC-DC Converter 15W to 60W for DIN mounting rail
The controlled DC-DC converters of the DFED/DFEC series by Power Mate supply 15 to 60W out of a highly compact enclosure size for fi tting on a TS35-7.5/-15 mounting rail. From the wide-range inputs 2:1 (9.5-18V, 18-36V, 36-75V) or 4:1 (9.5-36V, 18-75V) onwards, simple output voltages of 3.3V, 5V, 12V and 15V, dual voltages of ±12V, ±15V as well as triple outputs of 3.3/±12V, 3.3/±15V, 5/±12V, 5/±15V are available.
PLN-20 series and PLP-20 series LED power supplies
Ecopac Power has introduced two new Mean Well 20-watt LED power supplies with active power factor correction the PLN-20 series and PLP-20 series. The PLN-20 series is provided with an isolated plastic enclosure that meets IP64 rating. With the casing removed the PLP-20 series is supplied as an open frame unit; both units are ideal for any application that requires PFC in a low wattage power supply unit.
Switch-Mode Battery Chargers with Programmable JEITA Support
Summit Microelectronics has expanded its third-generation programmable battery charger integrated circuit (IC) family for single-cell Li-Ion, Li-Polymer, and Li-FePO4 powered systems.
Underwriters Laboratories introduces safety requirements for battery separators, aiming to further battery safety and integrity
Underwriters Laboratories (UL), a world leader in safety testing and certification, today announced the establishment of revised requirements addressing the safety of lithium batteries. The requirements, issued in December 2009 as UL Subject 2591, are designed specifically for separators, the porous film that keeps the anode and cathode components of batteries apart while still allowing ions to flow between them.
Astrodyne Introduces MicroVerter® Series
With the recent acquisition of RO Associates, Astrodyne has expanded its line of DC/DC converters to include the high-reliability, high-density MicroVerter® Series. This series ranges from 200-300 Watts available in ¾ brick. The MicroVerter Series features -40°C to +100°C operation (-55°C optional), current sharing, remote sense, switching frequency synch option, and trimmable output for rugged and extreme applications.
Power-One LPM615 compact modular power supply offers industry leading power density
Power-One announced the availability of its LPM615 1500W front-end AC-DC power supply family. This product is modular, accepting up to six output modules in order to provide customers with their exact voltage and current requirements with no minimum order quantities or set-up charges.
