FEATURES
? 48 Vdc to 12 Vdc 25 A current multiplier
- Operating from standard 48 V or 24 V PRM TM regulators
? High efficiency (>96%) reduces system power
consumption
? High density (85 A/in 3 )
? “Full Chip” V ? I Chip package enables surface mount,
low impedance interconnect to system board
? Contains built-in protection features:
DESCRIPTION
The V ? I Chip TM current multiplier is a high efficiency (>96%)
Sine Amplitude Converter TM (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; therefore
capacitance normally at the load can be located at the input to
the Sine Amplitude Converter. Since the K factor of the
VTM48EF120T025A00 is 1/4, the capacitance value can be
reduced by a factor of 16, resulting in savings of board area,
materials and total system cost.

Short Circuit
The VTM48EF120T025A00 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
- Overtemperature
? Provides enable / disable control,
internal temperature monitoring
? ZVS / ZCS resonant Sine Amplitude Converter topology
? Less than 50oC temperature rise at full load
in typical applications
TYPICAL APPLICATIONS
enhanced thermal management due to a large thermal
interface area and superior thermal conductivity. The high
conversion efficiency of the VTM48EF120T025A00 increases
overall system efficiency and lowers operating costs compared
to conventional approaches.
The VTM48EF120T025A00 enables the utilization of Factorized
Power Architecture TM which provides efficiency and size
benefits by lowering conversion and distribution losses and
promoting high density point of load conversion.
