Description
The EBVW020A0B series of dc-dc converters are a new generation of DC/DC power modules designed to support 9.6 -12Vdc
intermediate bus applications where multiple low voltages are subsequently generated using point of load (POL) converters, as
well as other application requiring a tightly regulated output voltage. The EBVW020A0B series operate from an input voltage
range of 36 to 75Vdc, and provide up to 20A output current at output voltages from 6.0Vdc to 12.0Vdc, and 240W output power
from output voltages of 12.1Vdc to 13.2Vdc in a DOSA standard eighth brick. The converter incorporates digital control,
synchronous rectification technology, and innovative packaging techniques to achieve efficiency reaching 95.4% peak at 12Vdc
output. This leads to lower power dissipations such that for many applications a heat sink is not required. Standard features
include on/off control, output overcurrent and over voltage protection, over temperature protection, input under and over
voltage lockout. Optional features include output voltage remote sense and trim from 6.0Vdc to 13.2Vdc, passive droop paralleling,
and base plate for heat sink or cold wall applications.
The output is fully 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 an integrated part
of sophisticated 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 fast-acting fuse with a maximum rating
of 15 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.

Test Configurations
Design Considerations
Input Source Impedance
The power module should be connected to a low ac-impedance
source. A highly inductive source impedance can affect the
stability of the power module. For the test configuration in
Figure 12, a 220μF electrolytic capacitor, Cin, (ESR<0.7 at
100kHz), mounted close to the power module helps ensure the
stability of the unit. If the module is subjected to rapid on/off
cycles, a 330μF input capacitor is required. Consult the factory
for further application guidelines.
Safety Considerations
Note: Measure input reflected-ripple current with a simulated
source inductance (LTEST) of 12 µH. Capacitor CS offsets
possible battery impedance. Measure current as shown above.
Figure 12. Input Reflected Ripple Current Test Setup.
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 2nd Ed.,
CSA C22.2 No. 60950-1 2nd Ed., and VDE0805-1 EN60950-1 2nd
Ed.
If the input source is non-SELV (ELV or a hazardous voltage
greater than 60 Vdc and less than or equal to 75Vdc), for the
module’s output to be considered as meeting the requirements
for safety extra-low voltage (SELV), all of the following must be
true:
Note: Use a 1.0 µF ceramic capacitor and a 10 µF aluminum or
tantalum capacitor. Scope measurement should be made
using a BNC socket. Position the load between
51 mm and 76 mm (2 in. and 3 in.) from the module.

Note: All measurements are taken at the module terminals. When


The input source is to be provided with reinforced
insulation from any other hazardous voltages, including
the ac mains.

One VIN pin and one VOUT pin are to be grounded, or both
the input and output pins are to be kept floating.

The input pins of the module are not operator accessible.

Another SELV reliability test is conducted on the whole
system (combination of supply source and subject
module), as required by the safety agencies, to verify that
under a single fault, hazardous voltages do not appear at
the module’s output.
Note: Do not ground either of the input pins of the module
without grounding one of the output pins. This may
allow a non-SELV voltage to appear between the output
pins and ground.
The power module has safety extra-low voltage (SELV) outputs
when all inputs are SELV.
The input to these units is to be provided with a maximum 15 A
fast-acting (or time-delay) fuse in the unearthed lead.
The power module has internally generated voltages exceeding
safety extra-low voltage. Consideration should be taken to
restrict operator accessibility.

Feature Descriptions
Overcurrent Protection
To provide protection in a fault output overload condition, the
module is equipped with internal current-limiting circuitry and
can endure current limiting continuously. If the overcurrent
condition causes the output voltage to fall greater than 4.0V
from Vo,set, the module will shut down and remain latched off.
The overcurrent latch is reset by either cycling the input power
or by toggling the on/off pin for one second. If the output
overload condition still exists when the module restarts, it will
shut down again. This operation will continue indefinitely until
the overcurrent condition is corrected.
A factory configured auto-restart option (with overcurrent and
overvoltage auto-restart managed as a group) is also available.
An auto-restart feature continually attempts to restore the
operation until fault condition is cleared.
overvoltage latch is reset by either cycling the input power, or
by toggling the on/off pin for one second. If the output
overvoltage condition still exists when the module restarts, it
will shut down again. This operation will continue indefinitely
until the overvoltage condition is corrected.
A factory configured auto-restart option (with overcurrent and

An auto-restart feature continually attempts to restore the
operation until fault condition is cleared.
Overtemperature Protection
These modules feature an overtemperature protection circuit to
safeguard against thermal damage. The circuit shuts down the
module when the maximum device reference temperature is
exceeded. The module will automatically restart once the
reference temperature cools by ~25°C.
Input Under/Over voltage Lockout
At input voltages above or below the input under/over voltage
lockout limits, module operation is disabled. The module will
begin to operate when the input voltage level changes to within
the under and overvoltage lockout limits.
Remote On/Off
The module contains a standard on/off control circuit reference
to the VIN(-) terminal. Two factory configured remote on/off logic
options are available. Positive logic remote on/off turns the

Figure 16). The voltage between the remote-sense pins and the
output terminals must not exceed the output voltage sense
range given in the Feature Specifications table:

The amount of power delivered by the module is defined as the
voltage at the output terminals multiplied by the output current.
When using remote sense and trim, the output voltage of the
module can be increased, which at the same output current
would increase the power output of the module. Care should be
taken to ensure that the maximum output power of the module
remains at or below the maximum rated power (Maximum
rated power = Vo,set x Io,max).

Trim, Output Voltage Programming
Trimming allows the output voltage set point to be increased or
decreased; this is accomplished by connecting an external
resistor between the TRIM pin and either the VO(+) pin or the VO() pin.

For example, to trim-down the output voltage of the module by
20% to 9.6V, Rtrim-down is calculated as follows:

Although the output voltage can be increased by both the
remote sense and by the trim, the maximum increase for the
output voltage is not the sum of both. The maximum increase is
the larger of either the remote sense or the trim.

The voltage between the Vo(+) and Vo(–) terminals must not

shown in the Feature Specifications table. This limit includes
any increase in voltage due to remote-sense compensation and
output voltage set-point adjustment trim.
Although the output voltage can be increased by both the
remote sense and by the trim, the maximum increase for the
output voltage is not the sum of both. The maximum increase is
the larger of either the remote sense or the trim. The amount of
power delivered by the module is defined as the voltage at the
output terminals multiplied by the output current. When using
remote sense and trim, the output voltage of the module can be
increased, which at the same output current would increase the
power output of the module. Care should be taken to ensure
that the maximum output power of the module remains at or
below the maximum rated power (Maximum rated power =
VO,set x IO,max).
Thermal Considerations

Connecting an external resistor (Rtrim-down) between the T/C1 pin

tolerance should be ±1.0%.

The power modules operate in a variety of thermal
environments and sufficient cooling should be provided to help
ensure reliable operation.
Thermal 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.

Feature Descriptions (continued)
The thermal data presented here is based on physical
measurements taken in a wind tunnel, using automated
thermo-couple instrumentation to monitor key component
temperatures: FETs, diodes, control ICs, magnetic cores,
ceramic capacitors, opto-isolators, and module pwb
conductors, while controlling the ambient airflow rate and
temperature. For a given airflow and ambient temperature, the
module output power is increased, until one (or more) of the
components reaches its maximum derated operating
temperature, as defined in IPC-9592. This procedure is then
repeated for a different airflow or ambient temperature until a
family of module output derating curves is obtained.
Figure 19. Location of the thermal reference temperature TH2
for Base Plate module. Do not exceed 110 °C.
The output power of the module should not exceed the rated
power for the module as listed in the Ordering Information
table.
Although the maximum temperature of the power modules is
THx, you can limit this temperature to a lower value for
extremely high reliability.
Please refer to the Application Note “Thermal Characterization
Process For Open-Frame Board-Mounted Power Modules” for a
detailed discussion of thermal aspects including maximum
device temperatures.
Heat Transfer via Convection
Increased airflow over the module enhances the heat transfer
via convection. The thermal derating of figures 20 through 22
show the maximum output current that can be delivered by
each module in the indicated orientation without exceeding the
maximum THx temperature versus local ambient temperature
(TA) for air flows of, Natural Convection, 1 m/s (200 ft./min), 2
m/s (400 ft./min).
Heat-dissipating components are mounted on the top side of
the module. Heat is removed by conduction, convection and
radiation to the surrounding environment. Proper cooling can
be verified by measuring the thermal reference temperature
(THx). Peak temperature (THx) occurs at the position indicated in
Figure 18 and 19. For reliable operation this temperature should
not exceed the listed temperature threshold.
The use of Figures 20 is shown in the following example:
Example
What is the minimum airflow necessary for a EBVW020A0B
operating at VI = 48 V, an output current of 14A, and a
maximum ambient temperature of 70 °C in transverse

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 RoHScompliant through-hole products can be processed with pastethrough-hole Pb or Pb-free reflow process. If additional
information is needed, please consult with your GE
representative for more details.

BMP module will comply with J-STD-020 Rev. C
(Moisture/Reflow Sensitivity Classification for
Nonhermetic Solid State Surface Mount Devices) for both Pbfree solder profiles and MSL classification
procedures. BMP will comply with JEDEC J-STD-020C
specification for 3 times reflow requirement. The suggested Pbfree solder paste is Sn/Ag/Cu (SAC). The recommended linear
reflow profile using Sn/Ag/Cu solder is shown in Figure 23.
Peak Temp. 240 -245°C
The EBVW020 power module series are low profile in order to
be used in fine pitch system card architectures. As such,
component clearance between the bottom of the power
module and the mounting board is limited. Avoid placing
copper areas on the outer layer directly underneath the power
module. Also avoid placing via interconnects underneath the
power module.
For additional layout guide-lines, refer to FLT007A0Z Data
Sheet.
Through-Hole Lead-Free Soldering
Information
The RoHS-compliant, Z version, through-hole products use the
SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant
components. The non-Z version products use lead-tin (Pb/Sn)
solder and RoHS-compliant components. Both version modules
are designed to be processed through single or dual wave
soldering machines. The pins have an RoHS-compliant, pure tin
finish that is compatible with both Pb and Pb-free wave
soldering processes. A maximum preheat rate of 3C/s is

detailed in J-STD-033 Rev. A (Handling, Packing, Shipping and
Use of Moisture/Reflow Sensitive Surface Mount Devices).
Moisture barrier bags (MBB) with desiccant are required for MSL
ratings of 2 or greater. These sealed packages should not be
broken until time of use. Once the original package is broken,
the floor life of the product at conditions of 30°C and 60%
relative humidity varies according to the MSL rating (see J-STD025A). The shelf life for dry packed SMT packages will be a
minimum of 12 months from the bag seal date, when stored at
the following conditions: < 40° C, < 90% relative humidity.
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 GE Board Mounted Power Modules:
Soldering and Cleaning Application Note (AP01-056EPS).
EMC Considerations
The circuit and plots in Figure 24 shows a suggested
configuration to meet the conducted emission limits of
Level
EN55022 Class B. For further information on designing for EMC
compliance, please refer to the FLT007A0 data sheet.
