Delphi NC30 Series Non-Isolated Point of Load
DC/DC Power Modules: 12Vin, 0.9V-5Vout, 30A
The Delphi NC30 Series, 12V input, 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 NC30 series operates from a 12V nominal input, provides up
to 30A of power in a vertical or horizontal mounted through-hole
package and the output can be resistor- or voltage-trimmed from
0.9Vdc to 5.0Vdc. NC30 series has built-in current sharing control and
multiple NC30/NC40 series modules could be paralleled together to
provide even higher output currents. NC30 series provides a very cost
effective 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 7: Design Considerations

    DESIGN CONSIDERATIONS The NC30 is designed using two-phase synchronous buck topology. Block diagram of the converter is shown in Figure 25. The output can be trimmed in the range of 0.9Vdc to 5.0Vdc by a resistor from trim pin to ground. A remote sense function is provided and it is able to compensate for a drop from the output of converter to point of load.
  • Page 8: Over-Current And Short-Circuit Protection

    FEATURES DESCRIPTIONS (CON.) Input Under-Voltage Lockout The input under-voltage lockout prevents the converter from being damaged while operating when the input voltage is too low. The lockout occurs between 7.7V to 8.6V. Over-Current and Short-Circuit Protection The NC series modules have non-latching over-current and short-circuit protection circuitry.
  • Page 9: Output Voltage Programming

    FEATURES DESCRIPTIONS (CON.) Output Voltage Programming The output voltage of the NC series is trimmable by connecting an external resistor between the trim pin and output ground as shown Figure 31 and the typical trim resistor values are shown in Figure 32. The output can also be set by an external voltage connected to trim pin as shown in Figure 32.
  • Page 10: Thermal Consideration

    FEATURES DESCRIPTIONS (CON.) Voltage Margining Output voltage margining can be implemented in the NC30/NC40 modules by connecting a resistor, R from the Trim pin to the ground pin for margining up the output voltage. Also, the output voltage can be adjusted lower by connecting a resistor, R margin-down pin to the output pin.
