Fixed Ratio DC-DC Converter
DESCRIPTION
The VI Chip^® bus converter is a high efficiency (>95%) Sine
Amplitude Converter™ (SAC™) operating from a 330 to 365
Vdc primary bus to deliver an isolated, ratiometric output from
10.3 to 11.4 V. The Sine Amplitude Converter offers a low AC
impedance beyond the bandwidth of most downstream
regulators; therefore capacitance normally at the load can be
located at the input to the Sine Amplitude Converter. Since the
transformation ratio of the BCM352F110T300B00 is 1/32, the
capacitance value can be reduced by a factor of 1024x,
resulting in savings of board area, materials and
total system cost.
The BCM352F110T300B00 is provided in a VI Chip package
compatible with standard pick-and-place and surface mount
assembly processes. The co-molded VI Chip package provides
enhanced thermal management due to a large thermal
interface area and superior thermal conductivity. The high
conversion efficiency of the BCM352F110T300B00 increases
overall system efficiency and lowers operating costs compared
to conventional approaches.
