Product Description



The VI Chip VTM™ current multiplier is a high efficiency Sine

Amplitude Converter™ (SAC™) operating from a primary bus to

deliver a low voltage output. The SAC™ 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 SAC™. Since the K factor of the

VTM48KP015T050AB0 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.

CM Current Monitor

The VTM48KP015T050AB0 is provided in a 0623 ChiP format

compatible with standard pick-and-place surface mount

assembly processes. The higher conversion efficiency of the

VTM48KP015T050AB0 increases overall system efficiency and

lowers operating costs compared to conventional approaches.

Ordering Information

The VTM48KP015T050AB0 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.
