DESIGN CONSIDERATIONS  
TEST CONFIGURATIONS  
Input Source Impedance  
To maintain low noise and ripple at the input voltage, it is  
critical to use low ESR capacitors at the input to the  
module. A highly inductive source can affect the stability  
of the module. An input capacitance must be placed  
close to the modules input pins to filter ripple current and  
ensure module stability in the presence of inductive  
traces that supply the input voltage to the module.

FEATURES DESCRIPTIONS  
DESIGN CONSIDERATIONS (CON.)  
Remote On/Off  
Safety Considerations  
The DCS series power modules have an On/Off pin for  
remote On/Off operation. Both positive and negative  
On/Off logic options are available in the DCS series power  
modules.  
For safety-agency approval the power module must be  
installed in compliance with the spacing and separation  
requirements of the end-use safety agency standards.  
For the converter output to be considered meeting the  
requirements of safety extra-low voltage (SELV), the  
input must meet SELV requirements. The power module  
has extra-low voltage (ELV) outputs when all inputs are  
ELV.  
For positive logic module, connect an open collector  
(NPN) transistor or open drain (N channel) MOSFET  
between the On/Off pin and the GND pin (see figure32).  
Positive logic On/Off signal turns the module ON during  
the logic high and turns the module OFF during the logic  
low. When the positive On/Off function is not used, leave  
the pin floating or tie to Vin (module will be On).  
The input to these units is to be provided with a  
maximum 10A fuse in the ungrounded lead.  
For negative logic module, the On/Off pin is pulled high  
with an external pull-up 5kΩ resistor (see figure 33).  
Negative logic On/Off signal turns the module OFF during  
logic high and turns the module ON during logic low. If the  
negative On/Off function is not used, leave the pin floating  
or tie to GND. (module will be on)  
Input Under voltage Lockout  
At input voltages below the input under voltage lockout  
limit, the module operation is disabled. The module will  
begin to operate at an input voltage above the under  
voltage lockout turn-on threshold.  
Vo  
Vin  
Over-Current Protection  
ION/OFF  
To provide protection in an output over load fault  
condition, the unit is equipped with internal over-current  
protection. When the over-current protection is  
triggered, the unit enters hiccup mode. The units  
operate normally once the fault condition is removed.

Output Voltage Programming  
4.888  
3.096  
The output voltage of the DCS can be programmed to any  
voltage between 0.59Vdc and 5.0Vdc by connecting one  
resistor (shown as Rtrim in Figure 35) between the TRIM  
and GND pins of the module. Without this external  
resistor, the output voltage of the module is 0.59 Vdc. To  
calculate the value of the resistor Rtrim for a particular  
output voltage Vo, please use the following equation:  
2.182  
1.340  
Certain restrictions apply on the output voltage set point  
depending on the input voltage. These are shown in the  
Output Voltage vs. Input Voltage Set Point Area plot in  
Figure 36. The Upper Limit curve shows that for output  
voltages of 0.9V and lower, the input voltage must be lower  
than the maximum of 14V. The Lower Limit curve shows  
that for output voltages of 3.8V and higher, the input voltage  
needs to be larger than the minimum of 4.5V.

FEATURE DESCRIPTIONS (CON.)  
When an analog voltage is applied to the SEQ pin, the  
output voltage tracks this voltage until the output reaches  
the set-point voltage. The final value of the SEQ voltage  
must be set higher than the set-point voltage of the  
module. The output voltage follows the voltage on the  
SEQ pin on a one-to-one basis. By connecting multiple  
modules together, multiple modules can track their output  
voltages to the voltage applied on the SEQ pin.  
Voltage Margining  
Output voltage margining can be implemented in the DCS  
modules by connecting a resistor, R margin-up, from the Trim  
pin to the ground pin for margining-up the output voltage  
and by connecting a resistor, Rmargin-down, from the Trim pin  
to the output pin for margining-down. Figure 37 shows the  
circuit configuration for output voltage margining. If  
unused, leave the trim pin unconnected. A calculation tool  
is available from the evaluation procedure which  
computes the values of Rmargin-up and Rmargin-down for a  
specific output voltage and margin percentage.  
For proper voltage sequencing, first, input voltage is  
applied to the module. The On/Off pin of the module is  
left unconnected (or tied to GND for negative logic  
modules or tied to VIN for positive logic modules) so that  
the module is ON by default. After applying input voltage  
to the module, a minimum 10msec delay is required  
before applying voltage on the SEQ pin. This delay gives  
the module enough time to complete its internal power-up  
soft-start cycle. During the delay time, the SEQ pin  
should be held close to ground (nominally 50mV ± 20  
mV). This is required to keep the internal op-amp out of  
saturation thus preventing output overshoot during the  
start of the sequencing ramp. By selecting resistor R1  
(see Figure. 39) according to the following equation

Output Voltage Sequencing  
The DCS 12V 6A modules include a sequencing feature,  
EZ-SEQUENCE that enables users to implement various  
types of output voltage sequencing in their applications.  
This is accomplished via an additional sequencing pin.  
When not using the sequencing feature, either tie the SEQ  
pin to VIN or leave it unconnected.  
Figure 38: Sequential Start-up  
The voltage at the sequencing pin will be 50mV when  
the sequencing signal is at zero.  
DS_DCS12S0A0S06NFA_12072012  
13  
Power Good  
FEATURE DESCRIPTIONS (CON.)  
The DCS modules provide a Power Good (PGOOD)  
signal that is implemented with an open-drain output to  
indicate that the output voltage is within the regulation  
limits of the power module. The PGOOD signal will be  
de-asserted to a low state if any condition such as over  
temperature, over current or loss of regulation occurs that  
would result in the output voltage going ±10% outside the  
set point value. The PGOOD terminal should be  
connected through a pull up resistor (suggested value  
100KΩ) to a source of 5VDC or lower.  
After the 10msec delay, an analog voltage is applied to  
the SEQ pin and the output voltage of the module will  
track this voltage on a one-to-one volt bases until the  
output reaches the set-point voltage. To initiate  
simultaneous shutdown of the modules, the SEQ pin  
voltage is lowered in a controlled manner. The output  
voltage of the modules tracks the voltages below their  
set-point voltages on a one-to-one basis. A valid input  
voltage must be maintained until the tracking and output  
voltages reach ground potential.  
When using the EZ-SEQUENCETM feature to control  
start-up of the module, pre-bias immunity during startup is  
disabled. The pre-bias immunity feature of the module  
relies on the module being in the diode-mode during  
start-up. When using the EZ-SEQUENCETM feature,  
modules goes through an internal set-up time of 10msec,  
and will be in synchronous rectification mode when the  
voltage at the SEQ pin is applied. This will result in the  
module sinking current if a pre-bias voltage is present at  
the output of the module.  
Monotonic Start-up and Shutdown  
The DCS 6A modules have monotonic start-up and  
shutdown behavior for any combination of rated input  
voltage, output current and operating temperature range.

the SEQ pin.

THERMAL CURVES  
THERMAL CONSIDERATIONS  
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.

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.
