? Less than 50°C temperature rise at full load in typical
applications
DESCRIPTION
The V ? I Chip TM Bus Converter is a high efficiency (>95%) Sine
Amplitude Converter TM (SAC TM ) operating from a 38 to 55 Vdc
primary bus to deliver an isolated 12 V nominal, unregulated
secondary. The SAC offers a low AC impedance beyond the
bandwidth of most downstream regulators, meaning that
input capacitance normally located at the input of a 12 V
regulator can be located at the input to the SAC. Since the
K factor of the BCM48BH120T120A00 is 1/4, that capacitance
value can be reduced by a factor of 16x, resulting in savings of
board area, materials and total system cost.
The BCM48BH120T120A00 is provided in a V ? I Chip package
compatible with standard pick-and-place and surface mount
assembly processes. The V ? I Chip package provides flexible
thermal management through its low junction-to-case and
junction-to-board thermal resistance. With high conversion
efficiency the BCM48BH120T120A00 increases overall system
efficiency and lowers operating costs compared to
conventional approaches.
