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 +25°C. Flex uses
Telcordia SR-332 Issue 3 Method 1 to calculate the mean
steady-state failure rate and standard deviation (σ).
Telcordia SR-332 Issue 3 also provides techniques to
estimate the upper confidence levels of failure rates based
on the mean and standard deviation.

MTBF (mean value) for the PKE52XX = 4.93 Mh.
MTBF at 90% confidence level = 2.75 Mh
MTBF (mean value) for the PKE53XXX = 4.55 Mh.

Radiation-caused injury
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”. 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/UL 62368-1 or IEC/UL 623681. 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/UL 62368-1 with regards to safety.
Flex DC/DC converters are UL 62368-1 or UL 62368-1
recognized. 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.
Isolated DC/DC converters
The product provides functional insulation between input
and output according to IEC/UL 62368-1.
For functional insulated products (see Safety Certificate)
the output is considered as ES1 energy source if one of the
following conditions is met:
• The input source provides double or reinforced
insulation from the AC mains according to
IEC/UL 62368-1.

• The input source provides basic or supplementary
insulation from the AC mains and the product’s output is
reliably connected to protective earth according to
IEC/UL 62368-1.
• The input source is reliably connected to protective
earth and provides basic or supplementary insulation
according to IEC/UL 62368-1 and the maximum input
source voltage is 60 Vdc.
It is recommended to use a slow blow fuse 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 that imposes a short
circuit on the input source, this fuse will provide the
following functions:
• Isolate the fault 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

Output Voltage Adjust (see operating information)
Passive adjust
The resistor value for an adjusted output voltage is calculated by
using the following equations:
To adjust the output voltage upwards, a resistor is connected
between pins 5 and 6. The output voltage increases when the
resistance decreases. The resistance value is given by the equation:
Rou= 5.6 × (1.1406Voi— Vod) / (Vod — Voi), (KOhm); Vod is the
desired output voltage and Voi is the initial output voltage.
To adjust the output voltage downwards, a resistor is connected
between pins 4 and 5. The output voltage decreases when the
resistance decreases. The resistance value is given by the equation:
Rod= 6.3875 × (1.1585Vod —Voi) / (Voi — Vod), (KOhm); Vod is the
desired output voltage and Voi is the initial output voltage.

Output Voltage Adjust (see operating information)
Passive adjust
The resistor value for an adjusted output voltage is calculated by
using the following equations:
To adjust the output voltage upwards, a resistor is connected
between pins 5 and 6. The output voltage increases when the
resistance decreases. The resistance value is given by the equation:
Rou= 3.3 × (1.1515Voi— Vod)/(Vod — Voi),(KOhm); Vod is the desired
output voltage and Voi is the initial output voltage.
To adjust the output voltage downwards, a resistor is connected
between pins 4 and 5. The output voltage decreases when the
resistance decreases. The resistance value is given by the equation:
Rod= 3.8 × (1.1316Vod —Voi)/( Voi — Vod),(KOhm); Vod is the desired
output voltage and Voi is the initial output voltage.

Output Voltage Adjust (see operating information)
Passive adjust
The resistor value for an adjusted output voltage is calculated by
using the following equations:
To adjust the output voltage upwards, a resistor is connected
between pins 5 and 6. The output voltage increases when the
resistance decreases. The resistance value is given by the equation:
Rou= 30 × (1.1499Voi— Vod)/(Vod — Voi),(KOhm); Vod is the desired
output voltage and Voi is the initial output voltage.
To adjust the output voltage downwards, a resistor is connected
between pins 4 and 5. The output voltage decreases when the
resistance decreases. The resistance value is given by the equation:
Rod= 34.497 × (1.1331Vod —Voi)/( Voi — Vod),(KOhm); Vod is the
desired output voltage and Voi is the initial output voltage.

Layout recommendations
The radiated EMI performance of the product will depend on
the PWB layout and ground layer design. It is also important to
consider the stand-off of the product. 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 PWB
and improve the high frequency EMC performance.

Operating Information
Input Voltage
The input voltage range 18 to 75 Vdc. At input voltages
exceeding 75 V, the power loss will be higher than at normal
input voltage and TP1 must be limited to absolute max +110°C
for PKE52XX variants’ products and +115°C for PKE53XXX
variants’ products. The absolute maximum continuous input
voltage is 75 Vdc.
Short duration transient disturbances can occur on the DC
distribution and input of the product when a short circuit fault
occurs on the equipment side of a protective device (fuse or
circuit breaker). The voltage level, duration and energy of the
disturbance are dependant on the particular DC distribution
network characteristics and can be sufficient to damage the
product unless measures are taken to suppress or absorb this
energy. The transient voltage can be limited by capacitors and
other energy absorbing devices like zener diodes connected
across the positive and negative input conductors at a number
of strategic points in the distribution network. The end-user
must secure that the transient voltage will not exceed the
value stated in the Absolute maximum ratings. ETSI TR
100 283 examines the parameters of DC distribution networks
and provides guidelines for controlling the transient and
reduce its harmful effect.
Turn-off Input Voltage
The products 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 1 V.
Remote Control (RC)
The products are fitted with a
remote control function referenced
to the primary negative input
connection (-In), with negative and
positive logic options available.The
RC function allows the product to
be turned on/off by an external
device like a semiconductor or
mechanical switch. The RC pin has
an internal pull up resistor to +In.
The external device must provide a minimum required sink
current to guarantee a voltage not higher than maximum
voltage on the RC pin (see Electrical characteristics table).
When the RC pin is left open, the voltage generated on the
RC pin is 3 - 6 V.
The standard product is provided with “negative logic” (Active
Low) remote control. When the RC pin is left open or
connected to a voltage higher than 2.5V referenced to -In, the
product will be off when the input voltage is applied. To turn on
the product, the RC pin should be connected to -In. In
situations where it is desired to have the product to power up

automatically without the need for control signals or a switch,
the RC pin must be wired directly to -In.
The second option is “positive logic” (Active High) remote
control, which can be ordered by adding the suffix “P” to the
end of the part number. In this case, when the RC pin is left
open, the product starts up automatically when the input
voltage is applied. Turn off is achieved by connecting the RC
pin to the -In. The product will restart automatically when this
connection is opened.
See Design Note 021 for detailed information.
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. The
products 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 22 - 100 µF capacitor across the input of the
PKE52XX (15W variant) product or a 220 µF capacitor across
the input of the PKE53XXX (30W variant) product will ensure
stable operation. The capacitor is not required when powering
the product from an input source with an inductance below 10
µH. The minimum required capacitance value depends on the
output power and the input voltage. The higher output power
the higher input capacitance is needed. Approximately
doubled capacitance value is required for a 24 V input voltage
source compared to a 48 V input voltage source.
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. It is equally important to
use low resistance and low inductance PWB layouts and
cabling.
External decoupling capacitors will become part of the
product’s control loop. The control loop is optimized for a wide
range of external capacitance and the maximum
recommended value that could be used without any additional
analysis is found in the Electrical specification.
The ESR of the capacitors is a very important parameter.
Stable operation is guaranteed with a verified ESR value of >5
mΩ across the output connections.

Output Voltage Adjust (Vadj)
The products have an Output Voltage Adjust pin (Trim). This
pin can be used to adjust the output voltage above or below
Output voltage initial setting.
When increasing the output voltage, the voltage at the output
pins must be kept below the threshold of the over voltage
protection, (OVP) to prevent the product from shutting down.
At increased output voltages, the maximum power rating of
the product remains the same and the max output current
must be decreased correspondingly.
To increase the voltage the resistor should be connected
between the Trim pin and –Out pin. The resistor value of the
Output voltage adjust function is according to information
given under the Output section for the respective product.
To decrease the output voltage, the resistor should be
connected between the Trim pin and +Out pin.

Thermal Consideration
General
The products are designed to operate in different thermal
eviorments 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 each model provides the available output
current vs. ambient air temperature and air velocity at
VI = 48 V.
The product is tested on a 107 x 45 mm, 70 µm (2 oz),
1-layer test board in a wind box with 370 x 220 mm.

Over Temperature Protection (OTP)
The products are protected from thermal overload by an
internal over temperature shutdown circuit.
When TP1 as defined in thermal consideration section exceeds
115°C the product will shut down. The product will make
continuous attempts to start up (non-latching mode) and
resume normal operation automatically when the temperature
has dropped >5°C below the temperature threshold.
Over Voltage Protection (OVP)
The converters have output over voltage protection that will
prevent output voltage to exceed the specified value in
technical specification.
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. The
temperature at this position (TP1) should not exceed the
maximum temperatures in the table below. Temperature
above maximum TP1, measured at the reference point P1 are
not allowed and may cause permanent damage.
Position

Description
Reference point
(PKE52XX variant)
The converter will limit the outputvoltage to the maximum
level. Converters will resume normal operation automatically
after removal of the over voltage condition.
Over Current Protection (OCP)
The products include current limiting circuitry for protection at
continuous overload. The output voltage will decrease towards
zero for output currents in excess of max output current (max
IO). The product will resume normal operation after removal of
the overload. The load distribution should be designed for the
maximum output short circuit current specified.

Ambient Temperature Calculation
For products with base plate/heatsink the maximum allowed
ambient temperature can be calculated
By using the thermal resistance.
1.
The power loss is calculated by using the formula
[(1/η) - 1)] x output power - power losses (Pd).
η = efficiency of product, E.g. 89.9% = 0.899
2.
●
Find the thermal resistance (Rth) in the Thermal
Resistance graph found in the Output section for
each model. Calculate the temperature increase (AT). AT
= Rth x Pd
3. Max allowed ambient temperature is.
Max TP1 - AT.
E.g. PKE5316JPI at 2m/s: (Room temperature:25℃)
η = 0.87
Reference point on PKE53XXX variant
Rth = 7.85°C/W
