High power-density bus converter
21 January 2009
Power Electronics / Power Management
Vicor has released a 120 W, 1/32nd brick footprint BCM bus converter. The VIB0101THJ is a 48:12 V 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 device uses a sine amplitude converter (SAC) for a high power density of 51 W/cm³. The ‘half-chip’ package enables a low impedance interconnect to the system board and 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 aluminium electrolytic or expensive tantalum bulk capacitors.
