Delphi Series V48SR, 1/16
DC/DC Power Modules: 48V in, 15V, 4.4A out
The Delphi Series V48SR, 1/16
DC/DC converter, is the latest offering from a world leader in power
systems technology and manufacturing ― Delta Electronics, Inc. This
product family provides up to 66 watts of power or 25A of output current
(1.8V and below) in an industry standard 1/16
0.90"). The 15V output offers one of the highest output currents available
and provides up to 90.5% efficiency at full load. With creative design
technology and optimization of component placement, these converters
possess outstanding electrical and thermal performance, as well as
extremely high reliability under highly stressful operating conditions. All
modules are protected from abnormal input/output voltage, current, and
temperature conditions. For lower power needs with the 15V output, but
in a similar small form factor, please check out Delta S48SP (36W or
15V/2.3A) and S48SE (17W or 15V/1A) series standard DC/DC modules.

  • Page 6: Design Considerations

    DESIGN CONSIDERATIONS Input Source Impedance The impedance of the input source connecting to the DC/DC power modules will interact with the modules and affect the stability. A low ac-impedance input source is recommended. If the source inductance is more than a few µH, we advise adding a 10 to 100 µF electrolytic capacitor (ESR <...
  • Page 7 DESIGN CONSIDERATIONS Safety Considerations The power module must be installed in compliance with the spacing and separation requirements of the end-user’s safety agency standard, i.e., UL60950, CAN/CSA-C22.2 No. 60950-00 and EN60950: 2000 and IEC60950-1999, if the system in which the power module is to be used must meet safety agency requirements.

  • Page 8: Features Descriptions

    FEATURES DESCRIPTIONS Over-Current Protection The modules include an internal output over-current protection circuit, which will endure current limiting for an unlimited duration during output overload. If the output current exceeds the OCP set point, the modules will automatically shut down, and enter hiccup mode or latch mode, which is optional.
  • Page 9 FEATURES DESCRIPTIONS (CON.) When using remote sense and trim, the output voltage of the module is usually increased, which increases the power output of the module with the same output current. Care should be taken to ensure that the maximum output power does not exceed the maximum rated power.

  • Page 10: Thermal Considerations

    THERMAL CONSIDERATIONS Thermal management is an important part of the system design. To ensure proper, reliable operation, sufficient cooling of the power module is needed over the entire temperature range of the module. Convection cooling is usually the dominant mode of heat transfer. Hence, the choice of equipment to characterize the thermal performance of the power module is a wind tunnel.
