Product Description
The V
I Chip™ bus converter is a high efficiency (>96%),
narrow input range Sine Amplitude Converter
TM
(SAC
TM
)
operating from a 38.0 to 55 Vdc primary bus to deliver
an isolated 38.0 V to 55.0 V secondary. The bus
converter may be used to power non-isolated POL
converters or as an independent 38.0 – 55.0 V source.
Due to the fast response time and low noise of the bus
converter, the need for limited life aluminum electrolytic
or tantalum capacitors at the load is reduced—or
eliminated—resulting in savings of board area, materials
and total system cost.
The bus converter achieves a power density of 1017
W/in
3
in a V
I Chip package compatible with standard
pick-and-place and surface mount assembly process. The
V
I Chip package provides flexible thermal management
through its low junction-to-board and junction-to-case
thermal resistance. Owing to its high conversion
efficiency and safe operating temperature range, the bus
converter does not require a discrete heat sink in typical
applications. Low junction-to-case and junction-to-lead
thermal impedances assure low junction temperatures
and long life in the harshest environments.
