DC/DC convertors take the middle ground
With the addition of nine new mid-power models, the 300V-input Mini family now comprises 17 DC/DC convertors with output voltages from 2 to 48V and power levels from 100 to 250W
Mid-power convertors are cost-effective option
The 24V-input Mini family now comprises 16 models with output voltages from 3.3 to 48V DC and power levels from 100 to 200W
Vicor has released a high-power-density (above 1100W/in3) 320W PRM nonisolated regulator. Designated P045F048T32AL, this latest V-I Chip component is designed for high-performance 48V power applications such as servers, telecomms and ATE. This PRM provides a controlled factorised bus distribution voltage for powering downstream VTM current multipliers, creating fast, efficient, isolated, low-noise point-of-load (POL) convertors.
With an efficiency of 97% and matched with a 94% VTM unit, it enables direct 48V-to-load with 91% efficiency, eliminating the need for an intermediate 12V bus conversion stage and VRMs.
In combination, PRMs and VTMs form a complete DC/DC convertor subsystem offering all of the unique benefits of Vicor's Factorised Power Architecture (FPA): high density and efficiency, low-noise operation, architectural flexibility, extremely fast transient response, and elimination of bulk capacitance at the point of load.
A PRM+VTM chipset provides up to 100A or 300W for a 48V-direct-to-load density of over 500W/in3.

Alternatively, the PRM regulator may be used independently if isolation is not required.
The P045F048T32AL features adaptive loop compensation feedback.
This single-wire alternative to traditional remote sensing and feedback loops enables precise control of an isolated POL voltage without the need for either a direct connection to the load or for noise-sensitive, bandwidth-limiting, isolation devices in the feedback path.
A 320W PRM+VTM chipset to convert from 48V direct to 1V is available immediately from stock for US $53 in OEM quantities.
