Editor's Choice for high power density and thermal efficiency. The EVC-116-1300 has universal input range of 90 to 264 VAC, able to handle wide range standard of worldwide wall power input voltages and frequencies. The input frequency is 47 to 63 Hz. Efficiencies up to mid 90s depending on the input voltage, an industry best. The Power Factor Correction is 0.99 at 110 VACin and 0.96 at 220 VACin. The Iout noise and ripple is 10 percent of Iout max. The turn-on delay at full load is 3s max. Each unit is protected by short circuit protection with auto recovery, over voltage protection and over temperature protection. The EVC-116-1300 is also backed by Green Watt Power's five year warranty. CAN bus communication is a standard feature for unit status and control. The operating temperature range of the EVC-116-1300 is -23°C to 50ºC. The storage range is -40°C to 85ºC. The unit is rated for IP65 for the enclosure. The EVC is designed to meet UL/CSA, TUV and EN55002 Class A. GS Yuasa Batteries Help Power Orbital Science's Cygnus Spacecraft on Mission to ISS GS Yuasa Lithium Power, Inc. (GYLP) has released that its batteries provided electrical power to Orbital Sciences Corp.'s Cygnus cargo logistics spacecraft on its maiden voyage the International Space Station. GYLP's battery, built in Roswell Georgia, uses high energy density LSE190 lithium ion cells to provide power to Cygnus immediately after launch and during in-orbit operations. GS Yuasa's lithium ion batteries provide a low mass and highly reliable solution to power the Cygnus advanced maneuvering space vehicle. "The berthing of Cygnus at the ISS marks a great accomplishment for Orbital," said William Moll, GYLP president. "We are excited to be a part of their success, and we will continue to support Orbital in their future ISS Cargo Resupply Services missions." GYLP is under contract to provide flight batteries for the next eight resupply missions that Orbital will fly to the ISS through 2016. Magnetic Battery Stack with Cordless Charging Ability Ascent Solar Technologies, Inc., a manufacturer of consumer and off-grid products integrated with flexible thin-film photovoltaic modules, has released the EnerPlex Jumpr line of portable batteries, the Jumpr Stack. The Jumpr Stack is offered in a family pack of three 1,600 mAh batteries with a master power base. Each battery has the footprint of a standard credit card and is no thicker than a standard USB port. The Jumpr Stack batteries are capable of boosting uptime for most smartphones by 50 percent to 80 percent. What sets the Jumpr Stack's batteries apart is their ability to be charged by stacking the batteries on top of each other, without the need of any cable connection while resting on the master power base. 6 Battery Power * November/December 2013 60 Volt Fault-Protected, 50 mA Step-Down Charge Pump Provides Regulated Output with Input Current Doubling Linear Technology Corp. has announced the LTC3255, a versatile high voltage step-down switched capacitor converter that delivers up to 50 mA of output current. In applications where the input voltage exceeds twice the output voltage, a charge pump offers nearly twice the efficiency of an equivalent linear regulator, and provides a space-saving inductor-free alternative to switching DC/DC regulators. The LTC3255 produces a regulated output (2.4 V to 12.5 V adjustable) from a wide 4 V to 48 V input that is +60 V/-52 V tolerant. At no load, Burst Mode operation reduces VIN quiescent current to 16 µA, and 2:1 capacitive charge pumping extends output current capability to approximately twice the input current. The LTC3255 is well suited for a variety of applications such as industrial control, factory automation, sensors and supervisory control and data acquisition (SCADA) systems, housekeeping power supplies, plus currentboosting voltage regulators for 4 mA to 20 mA current loops. The LTC3255 operates either as a general purpose step-down charge pump with 2:1 or 1:1 conversion ratios, or it can operate as a current doubling shunt regulator. In normal mode, the conversion ratio is chosen based on VIN, VOUT, and load conditions, and switching between conversion modes is automatic. In shunt mode, the device is forced into 2:1 mode, enabling the LTC3255 to provide a regulated output voltage from a current source input with nearly two times the input current available at the load. For example, this feature enables a 4 mA current loop to power a 7.4 mA load continuously with a 3.3 V regulated output voltage. The LTC3255 withstands reverse-polarity input supplies down to -52 V and output short-circuit without damage. Safety features, including an output current limit and over-temperature protection further enhance robustness. The LTC3255 is available in a low-profile (0.75 mm) 3 mm by 3 mm 10-lead DFN and a 10-lead MSOP package, both with a backside metal pad for enhanced thermal performance. The Eand I-grade operating junction temperature is -40°C to 125°C. The H grade offers -40°C to 150°C operation and the high reliability MP grade is specified from -55°C to 150°C. 1,000-piece pricing for the E grade starts at $2.30 each, and devices are available from stock.
