V.I Chip, Inc. introduces 120 W ‘half-chip’ bus converter

23 DECEMBER 2008

Vicor announces the availability of a 120W, 1/32nd brick footprint BCM™ bus converter. The VIB0101THJ is a 48:12V surface- mount, non-regulated converter with 94.5% efficiency and can be used to power non-isolated POL converters or as an isolated voltage source for ATE, server, telecom and industrial control applications.
The VIB0101THJ uses a Sine Amplitude Converter (SAC™) for a high power density of 840 W/in3. The half inch square ‘half-chip’ package enables a low impedance interconnect to the system board and reduces the power system volume by 75% vs. similar power-level converters. The V.I Chip package provides flexible thermal management through its low junction-to-board and junction-to-case thermal resistance. The BCM’s low impedance SAC enables a 16x capacitance reduction – eliminating the need for limited-life aluminum electrolytic or expensive tantalum bulk capacitors. The bus converter increases overall system efficiency and lowers operating costs compared to conventional approaches.
