Delphi NE Series Non-Isolated Point of Load
DC/DC Modules: 4.5V~13.8Vin, 0.59V~5.1Vout, 20A
The Delphi NE 20A Series, 4.5 to 13.8V wide input, wide trim single
output, non-isolated point of load DC/DC converters are the latest
offering from a world leader in power systems technology and
manufacturing — Delta Electronics, Inc. The ND/NE product family is
the second generation, non-isolated point-of-load DC/DC power
modules for the datacom applications which cut the module size by
almost 50% in most of the cases compared to the first generation NC
series POL modules. The product family here provides 20A of output
current in a vertically or horizontally mounted through-hole package
and the output can be resistor trimmed from 0.59Vdc to 5.1Vdc. It
provides a very cost effective, high efficiency, and high density point
of load solution. 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.

  • Page 6: Design Considerations

    DESIGN CONSIDERATIONS The NE12S0A0V(H)20 uses a single phase and voltage mode controlled buck topology. The output can be trimmed in the range of 0.59Vdc to 5.1Vdc by a resistor from Trim pin to Ground. The converter can be turned ON/OFF by remote control with positive on/off (ENABLE pin) logic.
  • Page 7: Output Voltage Programming

    FEATURES DESCRIPTIONS (CON.) The ENABLE input can be driven in a variety of ways as shown in Figures 19 and 20. If the ENABLE signal comes from the primary side of the circuit, the ENABLE can be driven through either a bipolar signal transistor (Figure 18).If the enable signal comes from the secondary side, then an opto-coupler or other isolation devices must be used to bring the signal across the voltage isolation...
  • Page 8: Output Capacitance

    FEATURES DESCRIPTIONS (CON.) Voltage Margining Adjustment Output voltage margin adjusting can be implemented in the NE modules by connecting a resistor, R the Trim pin to the Ground for margining up the output voltage. Also, the output voltage can be adjusted lower by connecting a resistor, R , from the Trim pin to margin-down...
  • Page 9: Thermal Consideration

    THERMAL CONSIDERATION 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.
