Product Description
The Vicor’s 1323 ChiP VTM current multiplier is a high
efficiency (>95%) Sine Amplitude Converter™ (SAC™)
operating from a 0 to 55 Vdc primary bus to deliver a 0 to
2.3 Vdc 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 VTM48KP020x088AA1 is
1/24, the capacitance value can be reduced by a factor of 576,
resulting in savings of board area, materials and total system
cost.
The VTM48KP020x088AA1 is provided in Vicor’s 1323 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 VTM48KP020x088AA1 increases overall system
efficiency and lowers operating costs compared to conventional
approaches.
The VTM48KP020x088AA1 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.
