Description
The VI Chip^® Bus Converter is a high efficiency (>95%) Sine
Amplitude ConverterTM (SAC^TM) operating from a 330 to 365V_DC
primary bus to deliver an isolated ratiometric output voltage from
11.79 to 13.04V_DC. 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 regulator
can be located at the input to the SAC. Since the K factor of the
BCM352x125y300A00 is 1/28, that capacitance value can be
reduced by a factor of 784x, resulting in savings of board area,
materials and total system cost.
The BCM352F125y300A00 is provided in a VI Chip package
compatible with standard pick-and-place and surface mount
assembly processes. The VI Chip package provides flexible thermal
management through its low junction-to-case and junction-to-
board thermal resistance. With high conversion efficiency the
BCM352x125y300A00 increases overall system efficiency and
lowers operating costs compared to conventional approaches.
