Product Description
The Vicor’s 0623 ChiP VTM current multiplier is a high efficiency
(>93%) Sine Amplitude Converter™ (SAC™) operating from a
0 to 52VDC primary bus to deliver a 0 to 1.63VDC low voltage
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
VTM48RP015x050AB1 is 1/32, the capacitance value can be
reduced by a factor of 1024, resulting in savings of board area,
materials and total system cost.
The VTM48RP015x050AB1 is provided in Vicor’s 0623 ChiP
package compatible with standard pick-and-place assembly
processes. The co-molded ChiP package provides enhanced
thermal management due to a large thermal interface area and
superior thermal conductivity. The high conversion efficiency of
the VTM48RP015x050AB1 increases overall system efficiency and
lowers operating costs compared to conventional approaches.
The VTM48RP015x050AB1 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.
