VTM Current Multiplier VTM48Ex480y006A00 S CUNRTL S High Efficiency, Sine Amplitude Converter Features & Benefits Product Ratings 48V to 48V 6.3A current multiplier DC DC V = 26 55V I = 6.3A (Nominal) IN OUT Operating from standard 48V or 24V PRM Regulators V = 26 55V (No Load) K = 1 OUT High efficiency (>96%) reduces system power consumption Product Description 3 High density (21.8A/in ) The VI Chip current multiplier is a high efficiency (>96%) Sine Amplitude Converter (SAC) operating from a 26 to 55V DC Full Chip VI Chip package enables surface mount, primary bus to deliver an isolated output. The Sine Amplitude low impedance interconnect to system board Converter offers a low AC impedance beyond the bandwidth Contains built-in protection features against: of most downstream regulators therefore capacitance normally at the load can be located at the input to the Sine Amplitude Overvoltage Lockout Converter. Since the K factor of the VTM48EF480T006A00 is 1, Overcurrent the capacitance value can be reduced by a factor of 1, resulting in Short Circuit savings of board area, materials and total system cost. Overtemperature The VTM48EF480T006A00 is provided in a VI Chip package Provides enable / disable control, compatible with standard pick-and-place and surface mount assembly processes. The co-molded VI Chip package provides internal temperature monitoring enhanced thermal management due to a large thermal interface ZVS / ZCS resonant Sine Amplitude Converter topology area and superior thermal conductivity. The high conversion efficiency of the VTM48EF480T006A00 increases overall Less than 50C temperature rise at full load system efficiency and lowers operating costs compared to in typical applications conventional approaches. The VTM48EF480T006A00 enables the utilization of Factorized Typical Applications Power Architecture which provides efficiency and size benefits by lowering conversion and distribution losses and promoting high High-End Computing Systems density point-of-load conversion.
