Description
The ATL010A0X43-SR power modules are non-isolated dc-dc converters that can deliver up to 10A of output
current with full load efficiency of 93% at 3.3V output. These modules provide a precisely regulated output voltage
programmable via an external resistor from 0.75Vdc to 5.5Vdc over a wide range of input voltage (VIN = 9 – 18Vdc).
TM
The ATL010A0X43-SR series has a sequencing feature, EZ-SEQUENCE that enables designers to implement
various types of output voltage sequencing when powering multiple voltages on a board. Their open-frame
construction and small footprint enable designers to develop cost- and space-efficient solutions. In addition to
sequencing, standard features include remote On/Off, remote sense, output voltage adjustment, over current and
over temperature protection.

CAUTION: These power modules can be used in a wide variety of applications ranging from simple standalone
operation to an integrated part of sophisticated power architectures. To preserve maximum flexibility, no internal fuse
has been provided. Also, extensive safety testing has shown that no external fuse is required to protect the unit.
However, it is still recommended that some type of current-limiting power source be used to protect the module and
evaluated in the end-use equipment.

Design Considerations
CURRENT PROBE
TO OSCILLOSCOPE
The ATL010A0X43-SR module should be connected to a
low-impedance source. A highly inductive source can
affect the stability of the module. An input capacitance
must be placed directly adjacent to the input pin of the
module, to minimize input ripple voltage and ensure
module stability.

In a typical application, 4x47 µF low-ESR tantalum
capacitors (AVX part #: TPSE476M025R0100, 47µF 25V
100 mΩ ESR tantalum capacitor) will be sufficient to
provide adequate ripple voltage at the input of the
module. To minimize ripple voltage at the input, low
ESR ceramic capacitors are recommended at the input of
the module. Figure 26 shows input ripple voltage (mVpp) for various outputs with 4x47 µF tantalum capacitors

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,
i.e., UL 60950-1, CSA C22.2 No. 60950-1-03, and VDE
0850:2001-12 (EN60950-1) Licensed.
The ATL010A0X43-SR module is designed for low output
ripple voltage and will meet the maximum output ripple
specification with 1 µF ceramic and 10 µF tantalum
capacitors at the output of the module. However,
additional output filtering may be required by the system
designer for a number of reasons. First, there may be a
need to further reduce the output ripple and noise of the
module. Second, the dynamic response characteristics
may need to be customized to a particular load step
change.
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.
To reduce the output ripple and improve the dynamic
response to a step load change, additional capacitance at
the output can be used. Low ESR polymer and ceramic
capacitors are recommended to improve the dynamic
response of the module. For stable operation of the
module, limit the capacitance to less than the maximum
output capacitance as specified in the electrical
specification table.

ATL010A0X43-SR Non Isolated Module 12Vdc, Programmable:
9 – 18Vdc input; 0.75Vdc to 5.5Vdc Output; 10A output current
Feature Description
Remote On/Off
Overtemperature Protection
The ATL010A0X43-SR power modules feature an On/Off
pin for remote On/Off operation. The ATL010A0X43-SR
modules feature positive on/off logic. Positive Logic
On/Off signal, turns the module ON during a logic High on
the On/Off pin and turns the module OFF during a logic
Low.
To provide over temperature protection in a fault
condition, the unit relies upon the thermal protection
feature of the controller IC. The unit will shutdown if the
o
thermal reference point Tref, exceeds 125 C (typical), but
the thermal shutdown is not intended as a guarantee that
the unit will survive temperatures beyond its rating. The
module will automatically restart after it cools down.
For positive logic modules, the circuit configuration for
using the On/Off pin is shown in Figure 27. The On/Off
pin is an open collector/drain logic input signal (Von/Off)
that is referenced to ground. During a logic-high (On/Off
pin is pulled high internal to the module) when the
transistor Q1 is in the Off state, the power module is ON.
Maximum allowable leakage current of the transistor
when Von/off = VIN,max is 10µA. Applying a logic-low
when the transistor Q1 is turned-On, the power module is
OFF. During this state VOn/Off must be less than 0.3V.
When not using positive logic On/off pin, leave the pin
unconnected or tie to VIN.

Output Voltage Programming
The output voltage of the ATL010A0X43-SR module can
be programmed to any voltage from 0.75Vdc to 5.0Vdc
by connecting a resistor (shown as Rtrim in Figure 28)
between Trim and GND pins of the module. Without an
external resistor between Trim and GND pins, the output
of the module will be 0.7525Vdc. To calculate the value
of the trim resistor, Rtrim for a desired output voltage, use
the following equation:
⎡ 10500
⎤
Rtrim = ⎢

continuously. At the point of current-limit inception, the
unit enters hiccup mode. The unit operates normally once
the output current is brought back into its specified range.
The typical average output current during hiccup is 3 A.

The amount of power delivered by the module is defined
as the voltage at the output terminals multiplied by the
output current. When using the trim feature, 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 (Pmax = Vo,set x Io,max).
Voltage Margining
Output voltage margining can be implemented in the
ATL010A0X43-SR module series by connecting a
resistor, Rmargin-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 30 shows the circuit
configuration for output voltage margining. The POL
Programming Tool, available at www.lineagepower.com
under the Design Tools section, also calculates the
values of Rmargin-up and Rmargin-down for a specific output
voltage and % margin. Please consult your local Lineage

Feature Descriptions (continued)
Remote Sense
Voltage Sequencing
The ATL010A0X43-SR 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 30). The voltage between the Sense pin and
Vo pin must not exceed 0.5V.
The ATL010A0X43-SR series of modules include a
TM
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.
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 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 volt basis. By connecting multiple modules
together, customers can get multiple modules to track
their output voltages to the voltage applied on the SEQ
pin.
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 by 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 pin to the output pin.

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 of 10msec delay is required
before applying voltage on the SEQ pin. During this time,
potential of 50mV (± 10 mV) is maintained on the SEQ
pin. After 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 output
reaches the set-point voltage. To initiate simultaneous
shutdown of the modules, the SEQ pin voltage is lowered
in a controlled manner. 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-SEQUENCE feature to control
start-up of the module, pre-bias immunity feature during
start-up is disabled. The pre-bias immunity feature of the
module relies on the module being in the diode-mode
TM
during start-up. When using the EZ-SEQUENCE
feature, modules goes through an internal set-up time of
10msec, and will be in synchronous rectification mode
when voltage at the SEQ pin is applied. This will result in
sinking current in the module if pre-bias voltage is present
at the output of the module. When pre-bias immunity
TM
during start-up is required, the EZ-SEQUENCE feature
must be disabled. For additional guidelines on using EZSEQUENCETM feature of Austin LynxTM II, contact the

Thermal Considerations
Power modules operate in a variety of thermal
environments; however sufficient cooling should always
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 presented here is based on physical measurements
taken in a wind tunnel. The test set-up is shown in Figure
32. Note that the airflow is parallel to the short axis of the
module as shown in figure 31. The derating data applies
to airflow in either direction of the module’s short axis.

Heat Transfer via Convection
The thermal reference points, Tref1 and Tref2 used in the
specifications are shown in Figure 31. For reliable
operation these temperatures should not exceed 115oC.
The output power of the module should not exceed the
rated power of the module (Vo,set x Io,max).
Increased airflow over the module enhances the heat
transfer via convection. Thermal derating curves showing
the maximum output current that can be delivered at
different local ambient temperatures (TA) for airflow
conditions ranging from natural convection and up to
2m/s (400 ft./min) are shown in the Characteristics
Curves section.

Surface Mount Information
Pick and Place
The ATL010A0X43-SR modules use an open frame
construction and are designed for a fully automated
assembly process. The modules are fitted with a
label designed to provide a large surface area for pick
and place operations. The label meets all the
requirements for surface mount processing, as well as
safety standards, and is able to withstand reflow
o
temperatures of up to 300 C. The label also carries
product information such as product code, serial
number and the location of manufacture.
instructions may result in the failure of or cause
damage to the modules, and can adversely affect
long-term reliability.
In a conventional Tin/Lead (Sn/Pb) solder process
peak reflow temperatures are limited to less than
235oC. Typically, the eutectic solder melts at 183oC,
wets the land, and subsequently wicks the device
connection. Sufficient time must be allowed to fuse
the plating on the connection to ensure a reliable
solder joint. There are several types of SMT reflow
technologies currently used in the industry. These
surface mount power modules can be reliably
soldered using natural forced convection, IR (radiant
infrared), or a combination of convection/IR. For
reliable soldering the solder reflow profile should be
established by accurately measuring the modules CP
connector temperatures.

Nozzle Recommendations
The module weight has been kept to a minimum by
using open frame construction. Even so, these
modules have a relatively large mass when compared
to conventional SMT components. Variables such as
nozzle size, tip style, vacuum pressure and placement
speed should be considered to optimize this process.
The minimum recommended nozzle diameter for
reliable operation is 6mm. The maximum nozzle outer
diameter, which will safely fit within the allowable
component spacing, is 9 mm. Oblong or oval nozzles
up to 11 x 9 mm may also be used within the space

Storage and Handling
The recommended storage environment and handling
procedures for moisture-sensitive surface mount
packages 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-STD-033A).
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 Board Mounted Power
