Delphi NC40 Series Non-Isolated Point of Load
DC/DC Power Modules: 12Vin, 0.9V-5Vout, 40A
OPTIONS
The Delphi NC40 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 NC40 series operates from a 12V nominal input, provides up
to 40A 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. NC40 series has built-in current sharing control and
multiple NC30/NC40 series modules could be paralleled together to
provide even higher output currents. NC40 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.

DESIGN CONSIDERATIONS
The NC40 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.
The converter can be turned ON/OFF by remote control.
Positive on/off (ENABLE pin) logic implies that the
converter DC output is enabled when this signal is driven
high (greater than 2.4V) or floating and disabled when the
signal is driven low (below 0.8V). Negative on/off logic is
optional and could also be ordered.
The converter provides an open collector signal called
Power Good. The power good signal is pulled low when
output is not within ±10% of Vout or Enable is OFF.
The converter can protect itself by entering hiccup mode
against over current and short circuit condition. Also, the
converter will shut down when an over voltage protection
is detected.
FEATURES DESCRIPTIONS
ENABLE (On/Off)
The ENABLE (on/off) input allows external circuitry to put
the NC converter into a low power dissipation (sleep) mode.
Positive (active-high) ENABLE is available as standard.
Positive ENABLE (active-high) units of the NC series are
turned on if the ENABLE pin is high or floating. Pulling the
pin low will turn off the unit. With the active high function,
the output is guaranteed to turn on if the ENABLE pin is
driven above 2.4V. The output will turn off if the ENABLE
pin voltage is pulled below .8V.
The ENABLE input can be driven in a variety of ways as
shown in Figures 26, 27 and 28. If the ENABLE signal
comes from the primary side of the circuit, the ENABLE can
be driven through either a bipolar signal transistor (Figure
26) or a logic gate (Figure 27). 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 (please see Figure 28).

FEATURES DESCRIPTIONS (CON.)
Over Temperature Protection (OTP)
Input Under-Voltage Lockout
To provide additional over-temperature protection in a
fault condition, the unit is equipped with a non-latching
thermal shutdown circuit. The shutdown circuit engages
when the temperature of monitored component exceeds
approximately 130℃. The unit will cycle on and off while
the fault condition exists. The unit will recover from
shutdown when the cause of the over temperature
condition is removed.
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. When over current
condition occurs, the module goes into the non-latching
hiccup mode. When the over-current condition is
removed, the module will resume normal operation.
An over current condition is detected by measuring the
voltage drop across the high-side MOSFET. The voltage
drop across the MOSFET is also a function of the
MOSFET’s Rds(on). Rds(on) is affected by temperature,
therefore ambient temperature will affect the current limit
inception point.
The unit will not be damaged in an over current condition
because it will be protected by the over temperature
protection.
Remote Sense
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 NC30/NC40 (option code B). The converters will
current share to be within +/- 10% of each other. In
addition to connect the I-Share pin together for the current
sharing operation, the remote sense lines of the
paralleled units must be connected at the same point for
proper operation. Also, units are intended to be turned
on/enabled at the same time. Hot plugging is not
recommended. The current sharing diagram show in
Figure 30.
The NC30/NC40 provide Vo remote sensing to achieve
proper regulation at the load points and reduce effects
of distribution losses on output line. In the event of an
open remote sense line, the module shall maintain local
sense regulation through an internal resistor. The
module shall correct for a total of 0.4V of loss. The
remote sense connects as shown in Figures 29.

FEATURES DESCRIPTIONS (CON.)
To use voltage trim, the trim equation for the NC30 is
(please refer to Fig. 33) :
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.
The NC30A/40A module has a trim range of 0.9V to
5.0V. A plot of trim behavior is shown in Figure 33
Rt (kΩ) =
Rs (13.1Vt + Vout − 12.69)
0.9 Rs − Vout ( Rs + 1) + 12.69
Vout is the desired output voltage
Vt is the external trim voltage
Rs is the resistance between Trim and Ground (in KΩ)
Rt is the resistor to be defined with the trim voltage (in KΩ)
Below is an example about using this voltage trim equation :

The converter provides an open collector signal called Power
Good. This output pin uses positive logic and is open
collector. This power good output is able to sink 5mA and set
high when the output is within ±10% of output set point. The
power good signal is pulled low when output is not within
±10% of Vout or Enable is OFF.
Output Capacitance
There is no output capacitor on the NC series modules.
Hence, an external output capacitor is required for stable
operation. For NC40 modules, two external 6.3V/680µF
output low ESR capacitors in parallel (for example, OSCON)
are required for stable operation.
It is important to places these low ESR capacitors as close to
the load as possible in order to get improved dynamic
response and better voltage regulation, especially when the
load current is large. Several of these low ESR capacitors
could be used together to further lower the ESR.

THERMAL CONSIDERATION
Voltage Margining
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.
Output voltage margining can be implemented in the
NC30/NC40 modules by connecting a resistor, R margin-up,
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, Rmargin-down, from the Trim
pin to the output pin. Figure 34 shows the circuit
configuration for output voltage margining adjustment.
Hence, the choice of equipment to characterize the
thermal performance of the power module is a wind
tunnel.

Reflected Ripple Current and Output Ripple and
Noise Measurement
The measurement set-up outlined in Figure 35 has been
used for both input reflected/ terminal ripple current and
output voltage ripple and noise measurements on NC
series converters.
The following figure shows the wind tunnel
characterization setup. The power module is mounted
on a test PWB and is vertically positioned within the
wind tunnel.
Thermal Derating
Heat can be removed by increasing airflow over the
module. To enhance system reliability, the power
module should always be operated below the
maximum operating temperature. If the temperature
exceeds the maximum module temperature, reliability
of the unit may be affected.
The maximum acceptable temperature measured at
the thermal reference point is 125℃. This is shown in
Figure 36 &41.
