D12S1R227-2D, Non-Isolated, Power Block
DC/DC Power Modules: 7.0~13.2Vin, 0.8V~1.8V/25Aout
The Delphi D12S1R227-2D, surface mounted, power block is the latest
offering from a world leader in power systems technology and
manufacturing — Delta Electronics, Inc. The D12S1R227-2D is the latest
offering in the DXP30 family which was developed to address the
ever-growing demands of increased current and power densities in
networking applications while providing maximum flexibility for system
configuration, its benefits can easily be applied to other applications
transcending various market segments. The DXP30 family, containing all
necessary power components and boasting of a USABLE (55˚C, 200LFM)
current density of 60A/in
building block for a new open Digital Power Architecture developed to work
with either digital or analog controllers. Measured at 0.5”Wx1.0”Lx0.5”H and
rated at 25A of output current, the D12S1R227-2D is designed to operate
with an input voltage from 7V to 13.2V and provide an output voltage
adjustable from 0.8V to 1.8V in digitally defined step resolution of 1.62mV.
Multiple D12S1R227-2D can be used in parallel to serve applications where
output currents are in excess of 25A with limitation imposed only by the
control circuit, analog or digital. Designed for superior price/performance,
The D12S1R227-2D can provide 1.8V and 25A full load in ambient
temperature up to 55˚C with 200LFM airflow.
