TYPICAL APPLICATION
DESCRIPTION
The V
•
I Chip Voltage Transformer is a high efficiency (>91%)
Sine Amplitude Converter (SAC)
TM
operating from a 26 to 55 Vdc
primary bus to deliver an isolated output. The Sine Amplitude
Converter offers a low AC impedance beyond the bandwidth of
most downstream regulators, which means that capacitance
normally at the load can be located at the input to the Sine
Amplitude Converter. Since the K factor of the VIV0005TFJ is
1/40, that capacitance value can be reduced by a factor of
1600, resulting in savings of board area, materials and total
system cost.
The VIV0005TFJ is provided in a V
•
I Chip package compatible
with standard pick-and-place and surface mount assembly
processes. The co-molded V
•
I Chip package provides enhanced
thermal management due to large thermal interface area and
superior thermal conductivity. With high conversion efficiency
the VIV0005TFJ increases overall system efficiency and lowers
operating costs compared to conventional approaches.
The VIV0005TFJ enables the utilization of Factorized Power
Architecture
TM
providing efficiency and size benefits by lowering
conversion and distribution losses and promoting high density
point of load conversion.
