Delphi NC Series Non-Isolated Point of Loadwww.DataSheet4U.com
DC/DC Power Modules: 12Vin, 0.9V-5Vout, 60A
The Delphi NC 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. This product family provides up to 60A of power in a vertical or
horizontal mounted through-hole package. The NC12S0A0V60 will
provide up to 60A of output current and the output can be resistor- or
voltage-trimmed from 0.9Vdc to 5.0Vdc. It 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.

Remote Sense
Remote sense compensates for voltage drops on the
output by sensing the actual output voltage at the point
of load. The module will compensate for a maximum
drop of 400mV. The remote sense connects as shown
in Figures 29.
This limit includes any increase in voltage due to
remote sense compensation and output voltage set
point adjustment (trim).

Under Voltage Lockout
The undervoltage lockout prevents the converter from
operating when the input voltage is too low. The lockout
occurs between 8.3V to 9.4V. This allows more flexibility
in designing and ensures operation on supply lines with
large tolerances
Over Current and Short-Circuit Protection
When over current condition occurs, the converter enters
hiccup mode. Ambient temperature influences the current
limit inception point since resistance of MOSFET rises
with temperature. The unit will not be damaged in an over
current condition because it will be protected by the over
temperature protection.
Over Temperature Protection (OTP)
The over temperature protection is non-latching and a
temperature sensor monitors the temperature of the PCB
near one the main MOSFETS. If temperature exceeds a
threshold of 130(typ.) the converter will shut down.
When the substrate temperature has decreased by 25
the converter will automatically restart.
Over Voltage Protection (OVP)
The converter will shut down when an output over voltage
is detected. Once the OVP condition is detected, the
controller will stop all PWM outputs and will turn on
low-side MOSFET driver to prevent any damage to load.
Current Sharing (optional)
The parallel operation of multiple converters is available
with the NC60 (option code B). The converter will share to
be within +/ - 10% of load. Note the remote sense lines of
the parallel units must be connected at the same point for
proper operation in addition to the current share pins
being connected. Also, units are intended to be turned
on/enabled at the same time. Hot plugging is not
recommended. The current share diagram show in Figure
30.
