General Information
Reliability
The failure rate (λ) and mean time between failures
(MTBF= 1/λ) is calculated at max output power and an
operating ambient temperature (TA) of +40°C. Flex Power
uses Telcordia SR-332 Issue 4 Method 1 to calculate the
mean steady-state failure rate and standard deviation (σ).
Telcordia SR-332 Issue 4 also provides techniques to
estimate the upper confidence levels of failure rates based
on the mean and standard deviation.
Mean steady-state failure rate, λ
Std. deviation, σ
14 nFailures/h
3.6 nFailures/h
MTBF (mean value) for the PMU series = 71.84 Mh.
MTBF at 90% confidence level = 53.99 Mh

Safety Specification
General information
Flex DC/DC converters and DC/DC regulators are
designed in accordance with the safety standards
IEC 62368-1, EN 62368-1 and UL 62368-1 Audio/video,
information and communication technology equipment Part 1: Safety requirements
IEC/EN/UL 62368-1 contains requirements to prevent injury
or damage due to the following hazards:
•
•
•
•
•
•
Electrical shock
Electrically-caused fire
Injury caused by hazardous substances
Mechanically-caused injury
Skin burn
Radiation-caused injury
On-board DC/DC converters, Power interface modules and
DC/DC regulators are defined as component power
supplies. As components they cannot fully comply with the
provisions of any safety requirements without “conditions of
acceptability”. Clearance between conductors and between
conductive parts of the component power supply and
conductors on the board in the final product must meet the
applicable safety requirements. Certain conditions of
acceptability apply for component power supplies with
limited stand-off (see Mechanical Information for further
information). It is the responsibility of the installer to ensure
that the final product housing these components complies
with the requirements of all applicable safety standards and
regulations for the final product.
Component power supplies for general use shall comply
with the requirements in IEC/EN/UL 62368-1. Product
related standards, e.g. IEEE 802.3af Power over Ethernet,
and ETS-300132-2 Power interface at the input to telecom
equipment, operated by direct current (dc) are based on
IEC/EN/UL 60950-1 with regards to safety.
Flex DC/DC converters, Power interface modules and
DC/DC regulators are UL 62368-1 recognized and certified
in accordance with EN 62368-1. The flammability rating for
all construction parts of the products meet requirements for
V-0 class material according to IEC 60695-11-10, Fire
hazard testing, test flames – 50 W horizontal and vertical
flame test methods.
Non - isolated DC/DC regulators
The DC/DC regulator output is ES1 energy source if the
input source meets the requirements for ES1 according to
IEC/EN/UL 62368-1.

Output ripple and noise test setup
The module is designed for low ripple voltage at the module
output and will meet the maximum output ripple specification
with 0.1 µF ceramic and 10 µF tantalum at the output of the
module.
The loop compensation setting is designed to provide stability,
accurate line and load regulation and good transient
performance for a wide range of operating conditions. Inherent
from the implementation and normal to the product there will
be some low frequency ripple at the output, in addition to the
fundamental switching frequency output ripple. This low
frequency ripple is not related to instability of control loop. The
total output ripple and noise is maintained at a low level.

Operating information
Input Voltage
The input voltage range is 9 to 36 Vdc meets typical
requirements in 12 V DC and 24 V DC system used in
telecom, datacom, industrial and medical equipment.
Remote control and input undervoltage lockout
(EN/UVLO)
The products are fitted with
a remote control function
referenced to the negative
input connection (-In). The
remote control function
allows the product to be
turned on/off by an external
device like a semiconductor
or mechanical switch.
The standard product is provided with “positive logic”. An
external pull up resistor is required for EN pin. To turn on the
product, EN pin should be left open. To turn off the product,
EN pin should be connected to -In.
The device also supports adjustable input undervoltage
lockout setting by adding a voltage divider on EN/UVLO pin.
When EN voltage is below 0.37V, the device is in shutdown
mode. When it exceeds 1.2V, an internal 10 µA current source
is enabled and flows through the external voltage divider to
provide hysteresis. The high side and low side resistor values
could be calculated by Equation 1 and 2.

Equation 2
Input and Output Impedance
The impedance of both the input source and the load will
interact with the impedance of the product. It is important that
the input source has low characteristic impedance. If the input
voltage source contains significant inductance, the addition of
a capacitor with low ESR across the input of the product will
ensure stable operation.
External Input Capacitors
It is recommended to use a combination of ceramic capacitors
and an electrolytic capacitor on the input side. Additional 100
µF of non-ceramic capacitance is recommended for
applications with large transient load requirements. At least 50
V voltage rating is recommended for both type of capacitors to
cover the wide input voltage range.
External Output Capacitors
The output capacitors must have low ESR value to achieve
low output ripple voltage.
External output capacitors must be placed as close as
possible to VOUT pins of the product. Minimum two 47 µF
ceramic capacitors are recommended. It is important to use
low resistance and low inductance PCB layout and cabling for
effective capacitance.
Remote Sense (+S)
The products have remote sense that can be used to
compensate for voltage drops between the output and the
point of load. The sense traces should be located close to the
PWB ground layer to reduce noise susceptibility.
The internal resistor between +S and VOUT is 47Ω. If the
remote sense is not needed, +S should be connected to
VOUT.
Over Current Protection
The product is protected from over current conditions in hiccup
mode. When overcurrent condition exists for 128 continuous
clock cycles, a hiccup event is triggerred and SS is pulled low
for 8192 clock cycles. The product will resume normal
operation after removal of the overload.
Synchronization (SYNC)
It is possible to synchronize the product with an external clock
signal. Requirements for the external clock are listed.
•
•
•
•
•
Clock frequency: 360 kHz to 675 kHz
Clock maximum voltage amplitude: 13 V
Clock minimum pulse width: 50 ns
Clock minimum input logic high: 2 V
Clock maximum input low: 0.8 V
Power Good (PG)
The power good signal indicates proper operation of the
product and can also be used as an error flag indicator. The
PG pin is internally pulled up to VIN with 22kΩ resistor. If the
output voltage is greater than 108% or lower than 92% of its
nominal value. The Power Good signal will be low to indicate
that the output voltage is out of regulation.
Soft Start and Output Voltage Tracking (SS/TRK)
Once EN/UVLO pin voltage exceeds 1.2V increasing
threshold, the device initiates soft-start process. The soft start
time tss is set by Css from SS/TRK pin to AGND. A 47nF
capacitor is connected internally by default. The total
capacitance should be calculated by Equation 3.

The SS/TRK could also be used as tracking pin when
master-slave power supply tracking is required. The
function is achieved by dividing output voltage of master
device through resistor network RTKR1 and RTKR2.
A common application of coincident tracking is shown
below. Coincident tracking forces the master and slave
channels have the same output voltage ramp rate until
the slave voltage reaches its setpoint.
Typical coincident tracking diagram
Simply select same voltage divider for both master and
slave devices to implement a coincident tracking.
Choose RTRK1=RSET1 and RTRK2=RSET2. Conversely,
different voltage dividers for master and slave
implement ratiometric tracking, which sets output
voltage of slave to a fraction of master output voltage.
In all cases, ensure the final value of SS/TRK voltage of
slave should be at least 0.1V above VSET reference
voltage 0.8V.
Output Voltage Setting (VSET)
The products support output voltage setting by
connecting resistor RSET between VSET and AGND.
Typical output voltages and corresponding RSET values
are listed in table below.

Thermal Consideration
General
The products are designed to operate in different thermal
environments and sufficient cooling must be provided to ensure
reliable operation.
For products mounted on a PWB without a heat sink attached,
cooling is achieved mainly by conduction, from the pins to the
host board, and convection, which is dependent on the airflow
across the product. Increased airflow enhances the cooling of
the product. The Output Current Derating graph found in the
Output section for provides the available output current vs.
ambient air temperature and air velocity at
VI = 24 V.

Over Temperature Protection (OTP)
The internal thermal shutdown circuitry forces the device to
stop switching if TP4 exceeds 155 °C. The device reinitiates the
power up sequence with typical 8°C hysteresis.
Layout recommendations
The radiated EMI performance of the product will depend on
the PCB layout and ground layer design. If a ground layer is
used, it should be connected to the output of the product and
the equipment ground or chassis.
A ground layer will increase the stray capacitance in the PCB
and improve the high frequency EMC performance.
Further layout recommendations are listed below.
•
Definition of product operating temperature
The product operating temperatures is used to monitor the
temperature of the product, and proper thermal conditions can
be verified by measuring the temperature at positions P1, P2,
P3 and P4. The temperature at these positions TP1, TP2, TP3
and TP4 should not exceed the maximum temperatures in the
table below. The number of measurement points may vary with
different thermal design and topology. Temperatures above
maximum TP1, measured at the reference point P1 are not
allowed and may cause permanent damage.
Besides the terminals, there are extra pads for production
test located at the bottom side of the modules. (see Figure
1 Test Pads) Don’t place conductive trace, voids and other
pads beneath the module to prevent unexpected short.

connections.
•
Use large copper areas for power planes to minimize
conduction loss and thermal stress.
•
Keep AGND and PGND separate from one another. The
connection is made internally.
•
Use multiple via to connect the power planes to internal
layers for improved thermal performance.
•
Only S+ pin is provided on device. If negative sense
resistor is added from PGND to external S- terminal. The
sensing connections should be routed as differential pair
and preferably between ground planes. Avoid areas of
high electric or magnetic fields.

Soldering Information - Surface Mounting
Lead-free (Pb-free) solder processes
The surface mount product is intended for forced convection or
vapor phase reflow soldering in SnPb or Pb-free processes.
For Pb-free solder processes, a pin temperature (TPIN) in
excess of the solder melting temperature (TL, 217 to 221°C for
SnAgCu solder alloys) for more than 60 seconds and a peak
temperature of 245°C on all solder joints is recommended to
ensure a reliable solder joint.
The reflow profile should be optimised to avoid excessive
heating of the product. It is recommended to have a sufficiently
extended preheat time to ensure an even temperature across
the host PWB and it is also recommended to minimize the time
in reflow.
A no-clean flux is recommended to avoid entrapment of
cleaning fluids in cavities inside the product or between the
product and the host board, since cleaning residues may affect
long time reliability and isolation voltage.

Minimum Pin Temperature Recommendations
Pin number 16 is chosen as reference location for the minimum
pin temperature recommendation since this will likely be the
coolest solder joint during the reflow process.
For Pb-free solder processes, the product is qualified for MSL 3
according to IPC/JEDEC standard J-STD-020C.
During reflow TPRODUCT must not exceed 260 °C at any time.
Dry Pack Information
Surface mount versions of the products are delivered in
standard moisture barrier bags according to IPC/JEDEC
standard J-STD-033 (Handling, packing, shipping and use of
moisture/reflow sensitivity surface mount devices).
Using products in high temperature Pb-free soldering
processes requires dry pack storage and handling. In case the
products have been stored in an uncontrolled environment and
no longer can be considered dry, the modules must be baked
according to J-STD-033.

SnPb solder processes
For SnPb solder processes, a pin temperature (TPIN) in excess
of the solder melting temperature, (TL, 183°C for Sn63Pb37) for
more than 60 seconds and a peak temperature of 220°C is
recommended to ensure a reliable solder joint.
For dry packed products only: depending on the type of solder
paste and flux system used on the host board, up to a
recommended maximum temperature of 245°C could be used,
if the products are kept in a controlled environment (dry pack
handling and storage) prior to assembly.

Surface Mount Assembly
For double-sided assemblies, the solder joints on the topside
of the board are inverted and reflowed again. During the
second reflow, the module will be held in place by the surface
tension, which may prevent the components from falling off
under the gravitational force.
According to our test, this module is capable for upside-down
second reflow process. It also should be noted that different
process configuration might have different performance for
upside-down reflow, in that case, gluing might be required to
secured the module from falling off.
Delivery Package Information
The products are delivered in antistatic carrier tape
