FEATURES  
DESCRIPTION  
The V I ChipTM current multiplier is a high efficiency (>94%)  
Sine Amplitude ConverterTM (SACTM) 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  
VTM48EF040T050A00 is 1/12, the capacitance value can be  
reduced by a factor of 144, resulting in savings of board area,  
materials and total system cost.  
•
• 48 Vdc to 4 Vdc 50 A current multiplier  
TM  
- Operating from standard 48 V or 24 V PRM regulators  
• High efficiency (>94%) reduces system power  
consumption  
• High density (170 A/in3)  
•
• “Full Chip” V I Chip package enables surface mount,  
low impedance interconnect to system board  
• Contains built-in protection features:  
- Overvoltage Lockout  
- Overcurrent  
•
The VTM48EF040T050A00 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  
- Short Circuit  
enhanced thermal management due to a large thermal  
interface area and superior thermal conductivity. The high  
conversion efficiency of the VTM48EF040T050A00 increases  
overall system efficiency and lowers operating costs compared  
to conventional approaches.  
- Overtemperature  
• Provides enable / disable control,  
internal temperature monitoring  
• ZVS / ZCS resonant Sine Amplitude Converter topology  
The VTM48EF040T050A00 enables the utilization of Factorized  
Power ArchitectureTM which provides efficiency and size  
benefits by lowering conversion and distribution losses and  
promoting high density point of load conversion.  
• Less than 50ºC temperature rise at full load  
in typical applications
