Regulator facilitates direct 48 V-to-load power conversion with 91% efficiency
Vicor has introduced a high power (>1100 W/in3) 320W PRM non-isolated regulator. Designated P045F048T32AL, this latest V•I Chip component is designed for high-performance 48V power applications such as servers, telecom and ATE. It provides a controlled Factorized Bus distribution voltage for powering downstream VTM current multipliers, creating fast, efficient, isolated, low-noise Point-of-Load (POL) converters. With an efficiency of 97% and m...
Intelligent battery charger/power management IC
Portable system designers who want to guarantee that the battery charges at maximum available current during simultaneous system operation must typically build that functionality into the system with discrete components. By continuously monitoring the power needs of the system during operation and automatically adjusting charge current accordingly, AnalogicTech’s AAT3670 delivers the highest possible charge current to the battery and thereby m...
1A Step-Down DC/DC Converter and Two 300mA VLDO Regulators in a single IC
Linear Technology has announced the LTC3446, a 1A, 2.25 MHz, synchronous buck regulator with two 300mA VLDOs in a single monolithic IC. The input voltage range of 2.5V to 5.5V makes this triple output regulator ideal for single cell Li-Ion/Polymer, or multicell alkaline/NiCad/NiMH powered applications. It can generate output voltages as low as 0.8V from the buck regulator and 0.4V for each of the VLDOs, enabling it to power the latest generation ...
Front-Ends and Rectifiers provide up to 650W and power density of 11.2W/in³
UNIPOWER has announced additions to its Sigma Series of hot-swap front-ends and rectifiers. The new models, now rated at up to 650W, have the same 1U x 2U profile (40.6 x 83.8mm) and are only 279mm long. They also incorporate a number of features designed to make the power sources easy to use and easy to monitor, particularly when used with the customer friendly 19” shelf. At just 0.95Kg (2.05lbs ), they are also among the lightest units ava...
Energy-Efficient 18W Medical Power Supplies
SL Power Electronics Corporation, the company established following the merger of Condor DC Power and Ault, announces a 10 to18W switch mode power supply family designed to help medical equipment OEMs replace linear power supplies with a single, energy-efficient, globally compatible switch-mode power unit. The Ault MW172 family features a 100VAC to 240VAC Universal Input range and meets the Environmental Protection Agency’s (EPA) ENERGY STA...
LED driver is said to increase power density
Providing an adjustable output current of 1A from a SOT23 package, the ZXLD1360 LED driver from Zetex Semiconductors offers higher power density than alternative and much larger SO8 devices. A buck regulator device, it operates over a supply range of 7V to 30V and is capable of handling up to 24W of output power in a wide range of high power LED illumination applications. Achieving up to 95% efficiency, this LED driver’s thermally enhanced con...
Constant-current LED driver IC with PWM control
The A6280 from Allegro MicroSystems Europe is a new 3-bit constant current LED driver which enables users to minimise the number of components needed to drive LEDs with large pixel spacing. The new driver controls LED luminance using a pulse width modulation (PWM) scheme which gives the application the capability of displaying up to one billion colours. An external resistor is used to set the overall maximum current, which can be set over a wide ...
20kW high voltage power supplies from HiTek
HiTek Power has added the OL20K 20kW family to its range of high voltage power supplies, offering output voltages from 60kV to 200kV and beyond. The eight members of this family have been built to meet the requirements of ion beam and electron beam systems. In addition to standard units, the supplies can be customised to meet specific requirements. Each system consists of a converter, in a 6U, 19 inch rack-mounting unit, and a separate high vol...
