Product Description  
Absolute Maximum Ratings  
The V•I Chip Bus Converter Module is a high efficiency  
(>95%), narrow input range Sine Amplitude Converter  
(SAC) operating from a 38 to 55 Vdc primary bus to  
deliver an isolated 9.50 V to 13.8 V secondary. The BCM  
may be used to power non-isolated POL converters or as  
an independent 9.50 – 13.8 V source. Due to the fast  
response time and low noise of the BCM, the need for  
limited life aluminum electrolytic or tantalum capacitors  
at the load is reduced—or eliminated—resulting in  
savings of board area, materials and total system cost.

The BCM achieves a power density of 1017 W/in3 in a  
V•I Chip package compatible with standard pick-and-  
place and surface mount assembly process. The V•I Chip  
package provides flexible thermal management through  
its low junction-to-board and junction-to-case thermal  
resistance. Owing to its high conversion efficiency and  
safe operating temperature range, the BCM does not  
require a discrete heat sink in typical applications. Low

(1) The referenced junction is defined as the semiconductor having the highest temperature.  
This temperature is monitored by a shutdown comparator.  
impedances assure low junction temperatures and long
