Description
The EQD020 series DC-DC converters are a new generation of open-frame DC/DC power modules designed to
support a 3:1 input voltage range, that allows operation in both 24V or 48V nominal input voltage systems, thus
eliminating the need for separate power modules for each input voltage range. These single output DC-DC
converters operate over an input voltage range of 19 to 60 Vdc. The series is also designed to provide a tightly
regulated output voltage trim range of ± 10% VO,Set, with output current up to 20A at 3.3Vdc in an industry standard
eighth brick package. The output is isolated from the input, allowing versatile polarity configurations and grounding
connections. Built in filtering for both input and output minimizes the need for external filtering.

CAUTION: This power module is not internally fused. An input line fuse must always be used.
This power module can be used in a wide variety of applications, ranging from simple standalone operation to being
part of a complex power architecture. To preserve maximum flexibility, internal fusing is not included, however, to
achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a very
fast-acting surface mount fuse with a maximum rating of 6.3 A (see Safety Considerations section). Based on the
information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a
lower rating can be used. Refer to the fuse manufacturer’s data sheet for further information.

The power module should be connected to a low acimpedance source. Highly inductive source
impedance can affect the stability of the power
module. For the test configuration in Figure 16, a
33µF electrolytic capacitor (ESR<0.1Ω at 100 kHz),
mounted close to the power module helps ensure the
stability of the unit. Consult your sales representative
for further applications guidelines.

For safety-agency approval of the system in which the
power module is used, the power module must be
installed in compliance with the spacing and
separation requirements of the end-use safety agency
standard, i.e., UL60950-1, CSA C22.2 No. 60950-103, EN60950-1 and VDE 0805:2001-12.
These converters have been evaluated to the spacing
requirements for Basic Insulation, per the above
safety standards; and 1500 Vdc is applied from Vin to
Vout to 100% of outgoing production.
For end products connected to –48V dc nominal DC
MAINS (i.e. central office dc battery plant), no further
fault testing is required. For all input voltages, other
than DC MAINS, where the input voltage is less than
60V dc, if the input meets all of the requirements for
SELV, then:
ƒ The output may be considered SELV. Output
voltages will remain within SELV limits even with
internally-generated non-SELV voltages. Single
component failure and fault tests were performed
in the power converters.
ƒ One pole of the input and one pole of the output
are to be grounded, or both circuits are to be kept
floating, to maintain the output voltage to ground
voltage within ELV or SELV limits.

Feature Descriptions
Over Temperature Protection
Remote On/Off
These modules feature an overtemperature protection
circuit to safeguard against thermal damage. The
circuit shuts down and latches off the module when
the maximum device reference temperature is
exceeded. The module can be restarted by cycling
the dc input power for at least one second or by
toggling the remote on/off signal for at least one
second. If the auto-restart option (4) is ordered, the
module will automatically restart upon cool-down to a
safe temperature.
The EQD020 series power modules have primary
referenced remote On/Off. The remote on/off is open
collector compatible with the signal common
referenced to the negative input. The standard
remote on/off negative logic is such that a unit
operates (ON) when the remote on/off signal is low or
short circuit to minus VIN. A module will be OFF when
the remote on/off pin is open circuit or when the
remote on/off signal is high. Observe the maximum
external ON/OFF voltage, specified in the Feature
Specifications table, when connecting an external
source to the ON/OFF pin. The optional positive logic
remote on/off is such that a unit operates (ON) when
the remote on/off signal is high or open-circuit. A unit
will be OFF when the remote on/off signal is low or
short-circuited to minus VIN.
VIN(+)
ON/OFF
Von/off
The output over voltage protection scheme of the
modules has an independent over voltage loop to
prevent single point of failure. This protection feature
latches in the event of over voltage across the output.
Cycling the on/off pin or input voltage resets the
latching protection feature. If the auto-restart option
(4) is ordered, the module will automatically restart
upon an internally programmed time elapsing.
Remote sense
VO
Ion/off
Output Over Voltage Protection
The EQD020 series power modules have a Remote
Sense feature to minimize the effects of distribution
losses by regulating the voltage at the Remote Sense
pin (See Figure 20). The voltage between the Sense
pin and Vo pin must not exceed 0.33V.
COM
VIN(-)
Figure 19. Circuit configuration for using Remote
On/Off Implementation.
Overcurrent Protection
To provide protection in a fault (output overload)
condition, the unit is equipped with internal
current-limiting circuitry and can endure current
limiting continuously. At the point of current-limit
inception, the unit enters a hiccup mode. If the unit is
not configured with auto–restart, then it will latch off
following the over current condition. The module can
be restarted by cycling the dc input power for at least
one second or by toggling the remote on/off signal for
at least one second. If the unit is configured with the
auto-restart option (4), it will remain in the hiccup
mode as long as the overcurrent condition exists; it
operates normally, once the output current is brought
back into its specified range.
The amount of power delivered by the module is
defined as the output voltage multiplied by the output
current (Vo x Io). When using Remote Sense, the
output voltage of the module can increase, which, if
the same output is maintained, increases the power
output from the module. Make sure that the maximum
output power of the module remains at or below the
maximum rated power. When the Remote Sense
feature is not being used, connect the Remote Sense
pins to the output pins of the module.

placed between the Trim pin and Sense (-) decreases
the output voltage. Figure 21 shows the circuit
configuration using an external resistor. The trim
resistor should be positioned close to the module. If
the trim pin is not used then the pin shall be left open.
The following equations determine the required
external resistor value to obtain a percentage output
voltage change of Δ%.

Power modules operate in a variety of thermal
environments; however, sufficient cooling should be
provided to help ensure reliable operation.
Considerations include ambient temperature, airflow,
module power dissipation, and the need for increased
reliability. A reduction in the operating temperature of
the module will result in an increase in reliability. The
thermal data is based on physical measurements
taken in a wind tunnel. The test set-up is shown in
Figure 22.

The thermal reference point, Tref, used in the
specifications is shown in Figure 23. For reliable
operation, this temperature should not exceed the
value specified in the Feature Specifications Table.
Tyco Electronics Power Systems
The RoHS-compliant through-hole products use the
SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant
components. They are designed to be processed
through single or dual wave soldering machines. The
pins have an RoHS-compliant finish that is compatible
with both Pb and Pb-free wave soldering processes.
A maximum preheat rate of 3°C/s is suggested. The
wave preheat process should be such that the
temperature of the power module board is kept below
210°C. For Pb solder, the recommended pot
temperature is 260°C, while the Pb-free solder pot is
270°C max. Not all RoHS-compliant through-hole
products can be processed with paste-through-hole
Pb or Pb-free reflow process. If additional information
is needed, please consult with your Tyco Electronics
Power System representative for more details.
Post Solder Cleaning and Drying
Considerations
Post solder cleaning is usually the final circuit-board
assembly process prior to electrical board testing. The
result of inadequate cleaning and drying can affect
both the reliability of a power module and the
testability of the finished circuit-board assembly. For
guidance on appropriate soldering, cleaning and
drying procedures, refer to Tyco Electronics Board
Mounted Power Modules: Soldering and Cleaning
Application Note (AN04-001).
