FEATURES AND DESIGN
CONSIDERATIONS
Introduction
The DIM3R3/050 module is designed to simplify the task
and reduce the board space of an ATCA (Advanced
Telecommunications Computing Architecture) power
entry distribution requirements in the system board.
EMI Filtering
An internal EMI filter is designed for the ATCA board to
meet the system conducted emission requirements of
CISPR 22 Class B when used with Delta DC/DC
converters.
Figure 17 shows the EMI performance of DIM3R3 when
it worked with Delta power module Q48SH12025NRFA
(36~75Vin, 12V/25A output Quarter brick). It meets
CISPR 22 Class B requirement.
The main functionality of the module is to provide dual,
redundant -48V A/B Feed OR’ing, inrush protection for
hot swap capability, EMI filtering to attenuate the noise
generated by the downstream DC/DC converters, and a
72V output voltage for charging the holdup capacitor.
The module also has a management power supply
which provides an 8W, 3.3V management power and/or
a 5V/100mA output (optional) to power the blue LED per
PICMG 3.0 requirement.
The module provides A/B feed/fuse open alarm, over
current protection, over voltage protection, and over
temperature protection. It also provides input under
voltage lock-out and input reverse polarity protection.
A/B Feed OR’ing
To improve the total power distribution efficiency, four
internal MOSFETs are used to function as the OR’ing
diodes. A control circuit is designed to keep about
100mV voltage drop across MOSFET. During full load
operation, the MOSFETs are fully turned on. During light
load, the MOSFETs work under a high Rdson condition.
If the output current decreases to zero, the MOSFETs
will be turned off. This design provides module a reverse
voltage sustain function. The module shall not be
damaged from reverse polarity connection in the event
of mis-wiring of either input feeds at the shelf input
terminals. Furthermore, a fast shut down circuit is
designed for the negative current case. This design
protects the common DC bus against hard short faults at
the sourcing power supply output.
Hot Swap Functionality
The hot-swap function is designed to limit the inrush
current charged to the bulk capacitor of the down stream
bus converter. The current value and duration comply
with the PICMG 3.0’s Inrush Transient specs.
Although the inrush current for bulk capacitor is under
control, special attentions need to be paid to the current
for EMI filter because this circuit is in front of hot-swap
circuit.

Figure 11: EMI test result with Q48SH12025NRFA:
Holdup
Capacitor
(72V_CAP)
Charging
Current
An off line holdup capacitor (C_HLDP) is needed to
store energy for the holdup time requirement. C_HLDP
is charged to 72V (+/- 3% tolerance). For a fixed energy
storage requirement, high capacitor voltage reduces
capacitor capacitance and size. A constant current
circuit charges C_HLDP before its voltage reaches the
high limitation and isolates it from power train circuit.
The discharge switch will turn on if both A&B feeds have
dropped below –38V (typical). C_HLDP will be
connected to power train and provided the energy for
system operation.
C_HLDP is calculated by the following equation:
C _ HLDP 
2 * Power * T _ HLDP
72V 2  Vth 2
Where Power is the input power to the downstream
DC/DC converter; T_HLDP is the holdup time
requirement; Vth is the minimum input voltage threshold
of the downstream DC/DC converter.

FEATURES AND DESIGN
CONSIDERATIONS (CONTINUED)
The PICMG 3.0’s requirements for the 0 Vdc transient is
5mS with 50V/ms fall slew rate and 12.5 V/ms rise slew
rate. This requirement will lead to a 9.3ms T_HLDP
requirement assuming power is interrupted at -43Vdc
(Vth).
Considering power output is 300W, Vth is 43V,
C _ HLDP 
2 * 300 * 9.3
 1672(uF )
722  432
Transient Over Voltage Protection
The PICMG 3.0 requires the module work normally
under 200V/5μS and 100V/10μS input voltage transient.
DIM3R3/050 can meet the requirement. An internal TVS
with 80V/1500W peak pulse power rating will suppress
the 200V transient voltage. For the 100V pulse voltage,
the power train impedance will damp it below internal
components rating without shut down the module. When
input voltage of the module is higher than 81.8V, the
module will be turned off. The module will restart when
the input voltage drop down to 79.8V.
Management Power and Blue_LED Power
When the input voltage is at the threshold of discharge,
C_HLDP will go off line and the charge pump will
recharge it to 72V.
The discharge resistor for C_HLDP is not required,
because there is sufficient standby current in the module
to bleed the holdup capacitors from 75V to 60V within 1
second as specified in the PICMG 3.0. Furthermore a
bleed resistor will induce extra loss of the MOSFET of
the charging circuit.
Over-Current Protection
DIM3R3/050 provides two over current protection levels
to protect downstream DC/DC converter over power
rating. When the downstream DC/DC converter over
power rating and caused our output current exceeds the
low current limit level, the current will be kept for a
period of time before the module is shut down. After a
fixed delay time, the module will try to restart. If the
downstream DC/DC converter over power rating and
caused our output current exceeds the high current limit
level, the module will shut down immediately. Then it will
go through the same restarting procedure.
The module contains two isolated DC output. The first
output provides up to 8W of 3.3V (DIM3R3)
management power (reference to LOGIC_GND). This
power is used to power the IPM controller for the ATCA
board or to power up system controller for other
applications. The second isolated output, 5V/100mA, is
used to power the Blue LED per PICMG 3.0
requirement.
The management power is available as soon as the
input voltage levels are within –36Vdc to –75Vdc. The
output is short circuit and over voltage protected. The
module is in a hiccup mode under an OCP or short
output condition. The output voltage will keep constant
under over voltage status. No additional output
capacitors are required, but a 22µF tantalum/ceramic
and a 0.01µF to 0.1µF ceramic capacitors are highly
recommended to reduce the switching ripple and noise.
Higher output capacitance may be required in case of
large input line or output load transient conditions.
A/B Feed / Fuse Alarm (-48V_ALARM)
The input feeds A and B are monitored. The module will
send an opto-isolated signal if any of the feed is below
the voltage threshold (typical 35V). Therefore, the loss
of any A or B feed can be detected. The opto coupler
transistor on state indicates a normal status and off
state indicates a fault condition.
Input Under Voltage Lockout
The input under-voltage lockout prevents the module from
being damaged by low input voltage. When the input
voltage is lower than its threshold voltage, the module will
be turned off. The lockout occurs between -33.3V to
-35.3V.

THERMAL CONSIDERATIONS
THERMAL CURVES
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. 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.
