Reduce Your Power System Volume by 75%

December 19, 2009
By

The combination of 840 W/in3 power density and 94.5% efficiency from a half-inch square, ‘half-chip’ V•I Chip package enables the VIB0101THJ to achieve a 75% reduction in overall power-system volume compared to equivalent power-rated modules. The first of the new 1/32nd bricks, the VIB0101THJ Bus Converter Module (BCM™) provides an easy, fast and flexible approach to achieving higher overall system efficiency combined with reduced board-space and cost. Rated at 120W, the VIB0101THJ operates from a 38 to 55 Vdc primary bus to provide an isolated 12 V nominal, unregulated secondary. This can be used...

New 28V Micro DC-DC Converters for Commercial or MIL-COTS Power

June 25, 2009
By

The addition of eight new wide-input 28V quarter-brick Micro DC-DC converters from Vicor provide more choice for power designers in commercial, industrial or MIL-COTS applications. With efficiency up to 82%, these new converters operate from 28V nominal input with an input range of 9 to 36V. They offer nominal output voltages from 3.3 to 48VDC with a wide nominal output voltage trim range of 10% to 110%. The maximum power rating for the 12 to 48V output modules is 100W, whilst the 3.3V and 5.0V versions are rated for 50W maximum power. Four environmental...

New Demo Board Eases Accurate LED Driving

The new pre-regulator module (PRM™) demonstration board, from V.I. Chip, delivers constant-current accuracy of 99.7% for lower power consumption LED-driving applications. A standalone PRM provides adjustable non-isolated currents up to 240W (5A at 48V). When combined with a voltage transformation module (VTM™), the PRM produces isolated currents up to 100A using less than 1 W per 1000 Lumens generated. The constant-current PRM™ demonstration board provides precisely-regulated currents for direct-drive multi-LED applications which control LED intensity and brightness by current regulation. The board can be used as a standalone module to provide an adjustable non-isolated current...

New VI BRICK™ Advanced DC-DC Power Platform

By integrating V•I Chip™ technology into traditional brick packages, the new VI BRICK™ modular DC-DC power platform delivers significantly increased power capability and design flexibility. The family’s robust, low-profile brick packages facilitate both thermal management and through-hole assembly. The 45 modules within the VI BRICK™ family are optimised for a range of DC-DC configurations: Intermediate Bus Architecture or point-of-load (POL) designs that require multiple output voltages; flexible DC-DC regulation and transformation using Factorized Power™; and 48V DC-DC conversion using advanced Sine Amplitude Converter™ technology. With a fast transient response, VI BRICK™ modules also minimise...

V•I Chips Solve a Noise Problem

A small company located in the northeastern US specializing in rapid prototyping of harsh environment instrumentation and ocean-acoustic research was developing a sonar system designed to detect intruders in a particular area, eg for harbor defence. The new sonar system was being designed to transmit and receive signals that can then be interpreted to identify what has been detected, such as a swimmer or a small underwater vehicle. Vicor initially provided Micro modules for the prototype system, but the sonar system transmits a signal and waits to receive a reflected signal in response. During...
