Delphi NE Series Non-Isolated Point of Load
DC/DC Modules:
3.1~13.8Vin, 0.59V-5.1Vout, 6Aout
The Delphi NE 6A 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 6A 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 6A of output current in a vertically or horizontally
mounted through-hole miniature package and the output can be
resistor trimmed from 0.59Vdc to 5.1Vdc. It provides a very cost
effective, high efficiency, and high density point of load solution. With
creative
design
technology
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)06 uses a single phase and voltage mode controlled buck topology. The output can be trimmed from 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 18 and 19. If the ENABLE signal comes from the primary side of the circuit, the ENABLE can be driven through either a bipolar signal transistor (Figure 19).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. - Page 10 THERMAL CURVES (VERTICAL) NE12S0A0V06(standard) Output Current vs. Ambient Temperature and Air Velocity Output Current (A) @Vin=12V Vout=5.0V (Either Orientation) Natural Convection 100LFM 200LFM 300LFM 400LFM 500LFM 600LFM Figure 29: Output current vs. ambient temperature and air velocity @Vin=12V, Vout=5.0V (Either Orientation) NE12S0A0V06(standard) Output Current vs.
