Delphi NE Series Non-Isolated Point of Load
DC/DC Modules: 3.1~13.8Vin, 0.59V-5.1Vout, 3Aout
The Delphi NE 3A Series, 3.1~13.8V wide input, wide trim single
output, non-isolated point of load (POL) DC/DC converters are the
latest offering from a world leader in power systems technology and
manufacturing — Delta Electronics, Inc. The NE product family is
the second generation, non-isolated point-of-load DC/DC power
modules which cut the module size by almost 50% in most of the
cases compared to the first generation NC series POL modules. The
NE 3A product family provides an ultra wide input range to support
3.3V, 5V, 8V, 9.6V, and 12V bus voltage point-of-load applications and
it offers up to 3A of output current in a vertically or horizontally
mounted through-hole miniature package and the output can be
resistor trimmed from 0.59Vdc to 5.0Vdc. 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.

DESIGN CONSIDERATIONS
The NE12S0A0V(H)03 uses a single phase and voltage
mode controlled buck topology. The output can be
trimmed from 0.59Vdc to 5.0Vdc 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. The converter DC
output is disabled when the signal is driven low (below
0.4V). This pin is also used as the input turn on threshold
judgment. Its voltage is percent of Input voltage during
floating due to internal connection. So we do not suggest
using an active high signal (higher than 1.0V) to turn on
the module because this high level voltage will disable
UVLO function. The module will turn on when this pin is
floating and the input voltage is higher than the threshold.
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.
Safety Considerations
It is recommended that the user to provide a very
fast-acting type fuse in the input line for safety. The output
voltage set-point and the output current in the application
could define the amperage rating of the fuse.
FEATURES DESCRIPTIONS
Enable (On/Off)
The ENABLE (on/off) input allows external circuitry to put
the NE converter into a low power dissipation (sleep)
mode. Positive ENABLE is available as standard. With
the active high function, the output is guaranteed to turn
on if the ENABLE pin is driven above 1.0V. The output will
turn off if the ENABLE pin voltage is pulled below 0.4V.
Undervoltage Lockout
The ENABLE pin is also used as input UVLO function.
Leaving the enable floating, the module will turn on if the
input voltage is higher than the turn-on threshold and turn
off if the input voltage is lower than the turn-off threshold.
The default turn-on voltage is 3.0V with 300mV
hysteresis.
The turn-on voltage may be adjusted with a resistor
placed between the “Enable” pin and “Ground” pin. The
equation for calculating the value of this resistor is:
15.05 × (R + 6.46 )
+ 0.5
6.46 × R
= VEN _ RTH − 0.3V
V EN _ RTH =
VEN _ FTH
VEN _ FTH is the turn-off threshold
VEN _ RTH is the turn-on threshold

to the GND

FEATURES DESCRIPTIONS (CON.)
The ENABLE input can be driven in a variety of ways as
shown in Figures 26 and 27. 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).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 27).
Output Voltage Programming
The output voltage of the NE series is trimmable by
connecting an external resistor between the trim pin and
output ground as shown Figure 28 and the typical trim
resistor values are shown in Figure 29

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 2.7V to
3.0V.
Over-Current and Short-Circuit Protection
The NE 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 MOSFETs. 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 detection of the Rds(on) of MOSFETs also acts as
an over temperature protection since high temperature
will cause the Rds(on) of the MOSFETs to increase,
eventually triggering over-current protection.

FEATURES DESCRIPTIONS (CON.)
Output Capacitance
Voltage Margining Adjustment
There is internal output capacitor on the NE series
modules. Hence, no external output capacitor is required
for stable operation.
Output voltage margin adjusting can be implemented in
the NE modules by connecting a resistor, Rmargin-up, from
the Trim pin to the Ground 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 voltage source Vt. Figure 31 shows the circuit
configuration for output voltage margining adjustment.

THERMAL CONSIDERATION
THERMAL CURVES (VERTICAL)
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.
Thermal Testing Setup
Delta’s DC/DC power modules are characterized in
heated vertical wind tunnels that simulate the thermal
environments encountered in most electronics
equipment. This type of equipment commonly uses
vertically mounted circuit cards in cabinet racks in which
the power modules are mounted.
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. The space between the neighboring PWB
and the top of the power module is constantly kept at
6.35mm (0.25’’).

Heat can be removed by increasing airflow over the

module should always be operated below the maximum
operating temperature. If the temperature exceeds the
