Description
The QBVW033A0B series of dc-dc converters are a new generation of DC/DC power modules designed to support
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 QBVW033A0B series
operate from an input voltage range of 36 to 75Vdc and provide up to 33A output current at output voltages of 12Vdc
in an industry standard quarter brick. The converter incorporates digital control, synchronous rectification technology,
a fully regulated control topology, and innovative packaging techniques to achieve efficiency exceeding 96% at 12V
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.
The output is fully isolated from the input, allowing versatile polarity configurations and grounding connections. Builtin 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 30 A in the ungrounded input lead of the power supply (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. Highly inductive source impedance
can affect the stability of the power module. For the test
configuration in Figure 11, a 100μF electrolytic capacitor,
Cin, (ESR<0.7 at 100kHz), mounted close to the power
module helps ensure the stability of the unit.
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 11. Input Reflected Ripple Current Test Setup.
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.

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. 60950-1, and VDEEN60950-1.
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:

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
30 A fast-acting (or time-delay) fuse in the ungrounded
input lead.
The optional heat-plate is considered floating mid-point
from a spacing perspective between input and output.

Feature Descriptions
Output Overvoltage Protection
Overcurrent Protection
The module contains circuitry to detect and respond to
output overvoltage conditions. If the overvoltage condition
causes the output voltage to rise above the limit in the
Specifications Table, the module will shut down and remain
latched off. The 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 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.
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
below 8.0V, 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.
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 module on during a logic-high
voltage on the ON/OFF pin, and off during a logic low.
Negative logic remote on/off turns the module off during a
logic high, and on during a logic low. Negative logic, device
code suffix "1," is the factory-preferred configuration. The
On/Off circuit is powered from an internal bias supply,
derived from the input voltage terminals. To turn the power
module on and off, the user must supply a switch to control
the voltage between the On/Off terminal and the VIN(-)
terminal (Von/off). The switch can be an open collector or
equivalent (see Figure 14). A logic low is Von/off = -0.3V to
0.8V. The typical Ion/off during a logic low (Vin=48V, On/Off
Terminal=0.3V) is 147µA. The switch should maintain a
logic-low voltage while sinking 310µA. During a logic high,
the maximum Von/off generated by the power module is
8.2V. The maximum allowable leakage current of the
switch at Von/off = 2.0V is 10µA. If using an external voltage
source, the maximum voltage Von/off on the pin is 14.5V
with respect to the VIN(-) terminal.
If not using the remote on/off feature, perform one of the
following to turn the unit on:
For negative logic, short ON/OFF pin to VIN(-).
For positive logic: leave ON/OFF pin open.
Figure 14. Remote On/Off Implementation.
LINEAGE POWER
Overtemperature Protection
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.
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.
Load Sharing
For higher power requirements, the QBVW033A0B power
module offers an optional feature for parallel operation (-P
Option code). This feature provides a precise forced output
voltage load regulation droop characteristic. The output set
point and droop slope are factory calibrated to insure
optimum matching of multiple modules’ load regulation
characteristics. To implement load sharing, the following
requirements should be followed:

The Vout(+) and Vout(-) planes of all parallel modules
must be connected together with output traces from
each module as short as possible to common power
planes.

These modules contain means to block reverse current
flow upon start-up, when output voltage is present from
other parallel modules, eliminating the requirement for
external output ORing devices. However, output ORing
devices should be used, if fault tolerance is desired in
parallel applications. It is essential to use the modules
Remote On/Off pin to control module startup; and not
allow the module to startup upon application of Vin.
One parallel module must start at least 15ms (may be
reduced TBD) sooner than the remaining parallel
modules to insure that the pre-bias detection operates
correctly.

Heat Transfer via Convection
Thermal Considerations
Increased airflow over the module enhances the heat
transfer via convection. The thermal derating of figure 1721 shows 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 several air flow
conditions.
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. The thermal data presented here is based on
physical measurements taken in a wind tunnel.
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 15 and 16. For reliable
operation this temperature should not exceed the listed
temperature threshold.
The use of Figures 16 is shown in the following example:
Example
What is the minimum airflow necessary for a
QBVW033A0B operating at VI = 48 V, an output current of
20A, and a maximum ambient temperature of 60 °C in
transverse orientation.
Solution:
Given: Vin= 48V, IO = 20A, TA = 60 °C
Determine required airflow velocity (Use Figure 17):
Velocity = 0.5m/s (100 LFM) or greater.
TBD
Figure 16. Location of the thermal reference
temperature TH3 for Base plate module.
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 THx temperature of the power
modules is TBD °C, 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.

Layout Considerations
The QBVW033 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
FLTR100V10 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 module is
designed to be processed through single or dual wave
soldering machines. The pins have a RoHScompliant, pure tin 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

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 Lineage Power Board
Mounted Power Modules: Soldering and Cleaning
Application Note (AP01-056EPS).
