The products are compatible with the relevant clauses and
requirements of the RoHS directive 2011/65/EU and have a
maximum concentration value of 0.1% by weight in
homogeneous materials for lead, mercury, hexavalent
chromium, PBB and PBDE and of 0.01% by weight in
homogeneous materials for cadmium.
Exemptions in the RoHS directive utilized in Flex products
are found in the Statement of Compliance document.
The Mean Time Between Failure (MTBF) is calculated at full
output power and an operating ambient temperature (TA) of
+40°C. Different methods could be used to calculate the
predicted MTBF and failure rate which may give different
results. Flex currently uses Telcordia SR332.
Flex fulfills and will continuously fulfill all its obligations
under regulation (EC) No 1907/2006 concerning the
registration, evaluation, authorization and restriction of
chemicals (REACH) as they enter into force and is through
product materials declarations preparing for the obligations
to communicate information on substances in the products.
Predicted MTBF for the series is:
Quality Statement
Reliability
-
4.02 million hours according to Telcordia SR332, issue
1, Black box technique.
Telcordia SR332 is a commonly used standard method
intended for reliability calculations in IT&T equipment. The
parts count procedure used in this method was originally
modelled on the methods from
MIL-HDBK-217F, Reliability Predictions of Electronic
Equipment.
It assumes that no reliability data is available on the actual
units and devices for which the predictions are to be made,
i.e. all predictions are based on generic reliability
parameters.
The products are designed and manufactured in an
industrial environment where quality systems and methods
like ISO 9000, 6σ (sigma), and SPC are intensively in use to
boost the continuous improvements strategy. Infant
mortality or early failures in the products are screened out
and they are subjected to an ATE-based final test.
Conservative design rules, design reviews and product
qualifications, plus the high competence of an engaged
work force, contribute to the high quality of our products.
Warranty
Warranty period and conditions are defined in Flex General
Terms and Conditions of Sale.
Limitation of Liability
Flex does not make any other warranties, expressed or
implied including any warranty of merchantability or fitness
for a particular purpose
(including, but not limited to, use in life support
applications, where malfunctions of product can cause
injury to a person’s health or life).

Safety Specification
General information
Flex DC/DC converters and DC/DC regulators are
designed in accordance with safety standards IEC/EN/
UL60950, Safety of Information Technology Equipment.
IEC/EN/UL60950 contains requirements to prevent
injury or damage due to the following hazards:
•
•
•
•
•
•
Electrical shock
Energy hazards
Fire
Mechanical and heat hazards
Radiation hazards
Chemical hazards
On-board DC-DC converters are defined as component
power supplies. As components they cannot fully comply
with the provisions of any Safety requirements without
“Conditions of Acceptability”. 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 Directives for the final
product.
Component power supplies for general use should comply
with the requirements in IEC60950, EN60950 and
UL60950 “Safety of information technology equipment”.
There are other more product related standards, e.g.
IEEE802.3af “Ethernet LAN/MAN Data terminal equipment
power”, and ETS300132-2 “Power supply interface at the
input to telecommunications equipment; part 2: DC”, but
all of these standards are based on IEC/EN/UL60950 with
regards to safety.
Flex DC/DC converters and DC/DC regulators are
UL60950 recognized and certified in accordance with
EN60950.
The flammability rating for all construction parts of the
products meets requirements for V-0 class material
according to IEC 60695-11-10.
The products should be installed in the end-use
equipment, in accordance with the requirements of the
ultimate application. Normally the output of the DC/DC
converter is considered as SELV (Safety Extra Low
Voltage) and the input source must be isolated by
minimum Double or Reinforced Insulation from the primary
circuit (AC mains) in accordance with IEC/EN/UL60950.
Isolated DC/DC converters
It is recommended that a slow blow fuse with a rating
twice the maximum input current per selected product be
used at the input of each DC/DC converter. If an input filter
is used in the circuit the fuse should be placed in front of
the input filter.
In the rare event of a component problem in the input filter
or in the DC/DC converter that imposes a short circuit on
the input source, this fuse will provide the following
functions:
•
•
Isolate the faulty DC/DC converter from the input
power source so as not to affect the operation of
other parts of the system.
Protect the distribution wiring from excessive
current and power loss thus preventing
hazardous overheating.
The galvanic isolation is verified in an electric strength test.
The test voltage (Viso) between input and output is
1500 Vdc or 2250 Vdc for 60 seconds (refer to product
specification).
Leakage current is less than 1 μA at nominal input voltage.
24 V DC systems
The input voltage to the DC/DC converter is SELV (Safety
Extra Low Voltage) and the output remains SELV under
normal and abnormal operating conditions.
48 and 60 V DC systems
If the input voltage to Flex DC/DC converter is 75 Vdc or
less, then the output remains SELV (Safety Extra Low
Voltage) under normal and abnormal operating conditions.
Single fault testing in the input power supply circuit should
be performed with the DC/DC converter connected to
demonstrate that the input voltage does not exceed
75 Vdc.
If the input power source circuit is a DC power system, the
source may be treated as a TNV2 circuit and testing has
demonstrated compliance with SELV limits and isolation
requirements equivalent to Basic Insulation in accordance
with IEC/EN/UL60950.
Non-isolated DC/DC regulators
The input voltage to the DC/DC regulator is SELV (Safety
Extra Low Voltage) and the output remains SELV under
normal and abnormal operating conditions.

Stress in excess of Absolute Maximum Ratings may cause permanent damage. Absolute Maximum Ratings, sometimes referred to as no destruction limits, are
normally tested with one parameter at a time exceeding the limits of Output data or Electrical Characteristics. If exposed to stress above these limits, function and
performance may degrade in an unspecified manner.

Input Voltage
The input voltage range 2.95 to 3.65 Vdc makes the product
easy to use in intermediate bus applications when powered
by a regulated bus converter.
TBD
Turn-off Input Voltage
The DC/DC regulators monitor the input voltage and will turn
on and turn off at predetermined levels.
The minimum hysteresis between turn on and turn off input
voltage is 50mV.
Test set-up
Layout recommendation
The radiated EMI performance of the DC/DC regulator will
depend on the PCB layout and ground layer design.
It is also important to consider the stand-off of the DC/DC
regulator.
If a ground layer is used, it should be connected to the output
of the DC/DC regulator and the equipment ground or chassis.
A ground layer will increase the stray capacitance in the PCB
and improve the high frequency EMC performance.
Remote Control (RC) Inhibit
The products are fitted with a
remote control function referenced
to the primary negative input
connection (- In), positive logic. The
INHIBIT function allows the
regulator to be turned on/off by an
external device like a
semiconductor or mechanical
switch. The INHIBIT pin has an
internal pull up resistor to + In.
The regulator will turn on when the input voltage is applied
with the INHIBIT pin open. Turn off is achieved by connecting
the INHIBIT pin to the - In. To ensure safe turn off, the voltage
difference between INHIBIT pin and the - In pin shall be less
than 0.6V. The regulator will restart automatically when this
connection is opened.

External Capacitors
Output Voltage Adjust (Vadj)
Input capacitors:
The recommended input capacitors are determined by the
470 μF minimum capacitance and 700 mArms minimum
ripple current rating.
The DC/DC regulators have an Output Voltage Adjust pin
(Vadj). This pin can be used to adjust the output voltage above
or below Output voltage initial setting.
Output capacitors (optional):
The recommended output capacitance of 330 μF will allow
the module to meet its transient response specification as
defined in the electrical specification.
To increase or decrease the voltage the resistor should be
connected between the Vadj pin and GND pin. The resistor
value of the Output voltage adjust function is according to
information given under the Output section for the respective
product.
When using one or more non-ceramic capacitors, the
calculated equivalent ESR should be no lower than 4 mΩ
(7mΩ using the manufacturer’s maximum ESR for a single
capacitor).
Input And Output Impedance
The impedance of both the input source and the load will
interact with the impedance of the DC/DC regulator. It is
important that the input source has low characteristic
impedance. The regulators are designed for stable operation
without external capacitors connected to the input or output.
The performance in some applications can be enhanced by
addition of external capacitance as described under External
Decoupling Capacitors. If the input voltage source contains
significant inductance, the addition of a 100 μF capacitor
across the input of the regulator will ensure stable operation.
The capacitor is not required when powering the DC/DC
regulator from an input source with an inductance below
10 μH.
External Decoupling Capacitors
When powering loads with significant dynamic current
requirements, the voltage regulation at the point of load can
be improved by addition of decoupling capacitors at the load.
The most effective technique is to locate low ESR ceramic
and electrolytic capacitors as close to the load as possible,
using several parallel capacitors to lower the effective ESR.
The ceramic capacitors will handle high-frequency dynamic
load changes while the electrolytic capacitors are used to
handle low frequency dynamic load changes. Ceramic
capacitors will also reduce any high frequency noise at the
load.
It is equally important to use low resistance and low
inductance PCB layouts and cabling.
External decoupling capacitors will become part of the
control loop of the DC/DC regulator and may affect the
stability margins. As a “rule of thumb”, 100 μF/A of output
current can be added without any additional analysis. The
ESR of the capacitors is a very important parameter. Power
Modules guarantee stable operation with a verified ESR value
of >10 mΩ across the output connections.
For further information please contact your local Flex
representative.
Parallel Operation
Two regulators may be paralleled for redundancy if the total
power is equal or less than PO max. It is not recommended to
parallel the regulators without using external current sharing
circuits.
Remote Sense
The DC/DC regulators 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
PCB ground layer to reduce noise susceptibility. The remote
sense circuitry will compensate for up to 0.3v voltage drop
between output pins and the point of load.
If the remote sense is not needed +Sense should be left
open.
Over Current Protection (OCP)
The regulators include current limiting circuitry for protection
at continuous overload.
The output voltage will decrease towards zero for output
currents in excess of the over-current threshold. The regulator
will resume normal operation after removal of the overload.
The load distribution should be designed for the maximum
output short circuit current specified. The current limit
operation is a “hick up” mode current limit.

From the moment a valid input voltage is applied, the softstart control introduces a short time-delay (typically 5-10 ms)
before allowing the output voltage to rise.
The initial rise in input current when the input voltage first
starts to rise is the charge current drawn by the input
capacitors. Power-up is complete within 15 ms.
Auto-Track™ Function
Auto-Track was designed to simplify the amount of circuitry
required to make the output vltage from each module power
up and power down in sequence. The sequencing of two or
more supply voltages during power up is a common
requirement for complex mixed-signal applications, that use
dual-voltage VLSI ICs such as DSPs, micro-processors and
ASICs.

Thermal Consideration
General
The regulators are designed to operate in different thermal
environments and sufficient cooling must be provided to
ensure reliable operation.
Cooling is achieved mainly by conduction, from the pins to
the host board, and convection, which is dependant on the
airflow across the regulator. Increased airflow enhances the
cooling of the regulator.
The Output Current Derating graph found in the Output
section for each model provides the available output current
vs. ambient air temperature and air velocity at Vin = 3.3 V.
Margin Up/Down controls
The DC/DC regulator is tested on a 254 x 254 mm,
35 μm (1 oz), 8-layer test board mounted vertically in a wind
tunnel with a cross-section of 305 x 305 mm.
These controls allow the input voltage to be momentarily
adjusted, either up or down, by a nominal 5 %. This provides
a convenient method for dynamically testing the operation of
the load circuit over its supply margin or range. It can also be
used to verify the function of supply voltage supervisors.
Proper cooling of the DC/DC regulator can be verified by
measuring the temperature at positions P1, P2 and P3. The
temperature at these positions should not exceed the max
values provided in the table below.
Pre-Bias Startup Capability
This often occurs in complex digital systems when current
from another power source is backfed through a dual-supply
logic component, such as FPGA or ASIC.
The PMG(3.3/5.0V Vin) incorporate synchronous rectifiers, but
will not sink current during startup, or whenever the Inhibit pin
is held low. However, to ensure satisfactory operation of this
function, certain conditions must be maintained.
Note that the max value is the absolute maximum rating
(non destruction) and that the electrical Output data is
guaranteed up to Tref +85°C.
See Design Note 019 for further information.

Soldering Information - Surface mounting
Maximum regulator temperature requirements
The surface mount version of the product is intended for
convection or vapor phase reflow Pb-free processes. To
achieve a good and reliable soldering result, make sure to
follow the recommendations from the solder paste supplier,
to use state-of-the-art reflow equipment and reflow profiling
techniques as well as the following guidelines.
To avoid damage or performance degradation of the product,
the reflow profile should be optimized to avoid excessive
heating. The maximum product temperature shall be
monitored by attaching a thermocoupler to the top of the
main transformer.
A no-clean flux is recommended to avoid entrapment of
cleaning fluids in cavities inside of the DC/DC regulator. The
cleaning residues may affect long time reliability and isolation
voltage.
A sufficiently extended preheat time is recommended to
ensure an even temperature across the host PCB, for both
small and large devices. To reduce the risk of excessive
heating is also recommended to reduce the time in the reflow
zone as much as possible.
Minimum pin temperature recommendations
SnPb solder processes
Pin number 9 is chosen as reference location for the minimum
pin temperature recommendations since this will be the
coolest solder joint during the reflow process.
For conventional SnPb solder processes, the product is
qualified for MSL 1 according to IPC/JEDEC standard
J-STD-020C.
During reflow, TP must not exceed +225 °C at any time.
