Description
TM
The Micro TLynx series of power modules are non-isolated dc-dc converters that can deliver up to 12A of output
current. These modules operate over a wide range of input voltage (VIN = 2.4Vdc-5.5Vdc) and provide a precisely
regulated output voltage from 0.6Vdc to 3.63Vdc, programmable via an external resistor. Features include remote
On/Off, adjustable output voltage, over current and overtemperature protection, and output voltage sequencing
(APTH versions). A new feature, the Tunable LoopTM, allows the user to optimize the dynamic response of the
converter to match the load with reduced amount of output capacitance leading to savings on cost and PWB area.

The Micro TLynx module should be connected to a
low ac-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.
To minimize input voltage ripple, low-ESR ceramic
capacitors are recommended at the input of the module.
Figure 34 shows the input ripple voltage for various
output voltages at 3A of load current with 1x47 µF or
2x47 µF ceramic capacitors and an input of 5V. Figure
35 shows data for the 3.3Vin case, with 1x47µF or
2x37µF of ceramic capacitors at the input.

Output Filtering
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 ceramic and
polymer capacitors are recommended to improve the
dynamic response of the module. Figure 36 provides
output ripple information for different external
capacitance values at various Vo and for load currents
of 12A while maintaining an input voltage of 5V. Fig 37
shows the performance with a 3.3V input. For stable
operation of the module, limit the capacitance to less
than the maximum output capacitance as specified in
the electrical specification table. Optimal performance
of the module can be achieved by using the Tunable

The Micro TLynxTM modules are designed for low output
ripple voltage and will meet the maximum output ripple
specification with 0.1 µF ceramic and 10 µF ceramic
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.

Safety Considerations
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.
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.

LINEAGE POWER
The Micro TLynx modules feature an On/Off pin for
remote On/Off operation. Two On/Off logic options are
available. In the Positive Logic On/Off option, (device
code suffix “4” – see Ordering Information), the module
turns ON during a logic High on the On/Off pin and turns
OFF during a logic Low. With the Negative Logic
On/Off option, (no device code suffix, see Ordering
Information), the module turns OFF during logic High
and ON during logic Low. The On/Off signal is always
referenced to ground. For either On/Off logic option,
leaving the On/Off pin disconnected will turn the module
ON when input voltage is present.
For positive logic modules, the circuit configuration for
using the On/Off pin is shown in Figure 38. For positive
logic modules, the circuit configuration for using the
On/Off pin is shown in Figure 38. When the external
transistor Q1 is in the OFF state, Q2 is ON, the internal
PWM Enable signal is pulled low and the module is ON.
When transistor Q1 is turned ON, the On/Off pin is

once the output current is brought back into its specified
range.
To provide protection in a fault condition, the unit is
equipped with a thermal shutdown circuit. The unit will
shutdown if the overtemperature threshold of 130oC is
exceeded at the thermal reference point Tref . The
thermal shutdown is not intended as a guarantee that
the unit will survive temperatures beyond its rating.
Once the unit goes into thermal shutdown it will then
wait to cool before attempting to restart.

At input voltages below the input undervoltage lockout
limit, the module operation is disabled. The module will
begin to operate at an input voltage above the
undervoltage lockout turn-on threshold.

On/Off logic.
Output Voltage Programming
For negative logic On/Off modules, the circuit
configuration is shown in Fig. 39. The On/Off pin should
be pulled high with an external pull-up resistor
(suggested value for the 2.4V to 5.5Vin range is
3Kohms). When transistor Q1 is in the OFF state, the
On/Off pin is pulled high and the module is OFF. The
On/Off threshold for logic High on the On/Off pin
depends on the input voltage and its minimum value is
VIN – 1.6V. To turn the module ON, Q1 is turned ON
pulling the On/Off pin low.
The output voltage of the Micro TLynx module can be
programmed to any voltage from 0.6dc to 3.63Vdc by
connecting a resistor between the Trim+ and GND pins
of the module. Certain restrictions apply on the output
voltage set point depending on the input voltage. These
are shown in the Output Voltage vs. Input Voltage Set
Point Area plot in Fig. 40. The Upper Limit curve shows
that the entire output voltage range is available with the
maximum input voltage of 5.5V. The Lower Limit curve
shows that for output voltages of 1.8V and higher, the
input voltage needs to be larger than the minimum of
2.4V.

Remote Sense
TM
The Micro TLynx modules have a Remote Sense
feature to minimize the effects of distribution losses by
regulating the voltage at the SENSE pin. The voltage
between the SENSE pin and VOUT pin must not
exceed 0.5V. Note that the output voltage of the module
cannot exceed the specified maximum value. This
includes the voltage drop between the SENSE and Vout
pins. When the Remote Sense feature is not being
used, connect the SENSE pin to the VOUT pin.
LINEAGE POWER
The 5.5V Pico TLynx 12A modules can start into a
prebiased output as long as the prebias voltage is 0.5V
less than the set output voltage. Note that prebias
operation is not supported when output voltage
sequencing is used.
Output Voltage Sequencing
The APTH012A0X modules include a 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.

Data Sheet

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 final value of 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, multiple modules
can track their output voltages to the voltage applied on
the SEQ 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 10msec delay is
required before applying voltage on the SEQ pin. This
delay gives the module enough time to complete its
internal power-up soft-start cycle. During the delay time,
the SEQ pin should be held close to ground (nominally
50mV ± 20 mV). This is required to keep the internal opamp out of saturation thus preventing output overshoot
during the start of the sequencing ramp. By selecting
resistor R1 (see fig. 43) according to the following
equation
R1 =
voltage must be maintained until the tracking and output
voltages reach ground potential.
TM
When using the EZ-SEQUENCE feature to control
start-up of the module, pre-bias immunity 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 the voltage at the SEQ pin is applied. This will
result in the module sinking current if a pre-bias voltage
is present at the output of the module. When pre-bias
immunity during start-up is required, the EZTM
SEQUENCE feature must be disabled. For
additional guidelines on using the EZ-SEQUENCETM
feature please refer to Application Note AN04-008

Tunable LoopTM
TM
The 5V Pico TLynx 12A modules have a new feature
that optimizes transient response of the module called
TM
Tunable Loop .
External capacitors are usually added to the output of
the module for two reasons: to reduce output ripple and
noise (see Figures 36 and 37) and to reduce output
voltage deviations from the steady-state value in the
presence of dynamic load current changes. Adding
external capacitance however affects the voltage control
loop of the module, typically causing the loop to slow
down with sluggish response. Larger values of external
capacitance could also cause the module to become
unstable.
TM
The Tunable Loop allows the user to externally adjust
the voltage control loop to match the filter network
connected to the output of the module. The Tunable
TM
Loop is implemented by connecting a series R-C
between the SENSE and TRIM pins of the module, as
shown in Fig. 44. This R-C allows the user to externally
adjust the voltage loop feedback compensation of the
module.

application to meet output ripple and noise requirements
for 5Vin and 3.3Vin respectively. Selecting RTUNE and
CTUNE according to Table 2 will ensure stable operation
of the module.
In applications with tight output voltage limits in the
presence of dynamic current loading, additional output

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 45. The preferred airflow direction
for the module is shown in Figure 46.

Surface Mount Information
Pick and Place
The Micro TLynxTM 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.
Nozzle Recommendations
The module weight has been kept to a minimum by
using open frame construction. Variables such as
nozzle size, tip style, vacuum pressure and placement
speed should be considered to optimize this process.
The minimum recommended inside nozzle diameter
for reliable operation is 3mm. The maximum nozzle
outer diameter, which will safely fit within the allowable
component spacing, is 7 mm.
Bottom Side / First Side Assembly
This module is not recommended for assembly on the
bottom side of a customer board. If such an assembly
is attempted, components may fall off the module
during the second reflow process. If assembly on the
bottom side is planned, please contact Lineage Power
for special manufacturing process instructions.
Only ruggedized (-D version) modules with additional
epoxy will work with a customer’s first side assembly.
For other versions, first side assembly should be
avoided
Lead Free Soldering
The Micro TLynxTM modules are lead-free (Pb-free)
and RoHS compliant and fully compatible in a Pb-free
soldering process. Failure to observe the instructions
below may result in the failure of or cause damage to
the modules and can adversely affect long-term
reliability.

Power for special manufacturing process instructions.
The recommended linear reflow profile using Sn/Ag/Cu
solder is shown in Fig. 47. Soldering outside of the
recommended profile requires testing to verify results
and performance.
MSL Rating
TM
The Micro TLynx
modules have a MSL rating of 2.
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.
