Features & Benefits
Product Ratings
• 48VDC to 9.6VDC 25A current multiplier
VIN = 26 to 55V
IOUT = 25A (nom)
K = 1/5
nꢀOperating from standard 48V or 24V PRM™ Regulators
VOUT = 5.2 to 11.0V (no load)
• High efficiency (>95%) reduces system power
consumption
Description
• High density (85A/in3)
The VI Chip® current multiplier is a high efficiency (>95%)
Sine Amplitude Converter™ (SAC) operating from a
26 to 55VDC 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
VTM48EF096T025A00 is 1/5, the capacitance value can be
reduced by a factor of 25, resulting in savings of board area,
materials and total system cost.
• “Full Chip” VI Chip® package enables surface mount,
low impedance interconnect to system board
• Contains built-in protection features against:
nꢀOvervoltage Lockout
nꢀOvercurrent
nꢀShort Circuit
nꢀOvertemperature
• Provides enable / disable control,
internal temperature monitoring
The VTM48EF096T025A00 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 VTM48EF096T025A00 increases overall system
efficiency and lowers operating costs compared to conventional
approaches.
• ZVS / ZCS resonant Sine Amplitude Converter topology
• Less than 50ºC temperature rise at full load
in typical applications
Typical Applications
The VTM48EF096T025A00 enables the utilization of Factorized
Power Architecture™ which provides efficiency and size benefits
by lowering conversion and distribution losses and promoting
high density point of load conversion.
• High End Computing Systems
• Automated Test Equipment
• High Density Power Supplies
• Communications Systems
