Fixed Ratio DC-DC Converter
DESCRIPTION
The VI Chip^® bus converter is a high efficiency (>94%) Sine
Amplitude Converter™ (SAC™) operating from a 38 to 55 Vdc
primary bus to deliver an isolated, ratiometric output from
19.0 to 27.5 output. 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
BCM48BF240T300A00 is 1/2, the capacitance value can be
reduced by a factor of 4x, resulting in savings of board area,
materials and total system cost.
The BCM48BF240T300A00 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 BCM48BF240T300A00 increases
overall system efficiency and lowers operating costs compared
to conventional approaches.
