Description
Features
The S15 family of high efficiency, low power DC/DC
converters offer power levels that exceed other bricks
with similar footprints. They are targeted specifically at
the telecommunication, industrial electronics, mobile
telecommunication and distributed power markets.
With a wide input voltage range of 36-75V they are
available with output voltages of either 1. 5, 1.8, 2.5,
3.3, 5, 12 or 15 Volts. All models feature an input filter,
input
undervoltage
lockout,
overtemperature
protection, output current limiting and short circuit
protection. The fully enclosed, encapsulated
construction with aluminum heat spreader design
achieves very efficient heat transfer with no hot spots.
The use of patented design concepts facilitate
maximum power delivered with the highest efficiency
up to 90%. The converters combine creative design
concepts with highly derated power devices to achieve
very high reliability, high performance and low cost
solution to systems designers requiring maximum
power in small footprints.

Basic Operation And Functions
S15-48-15D is a high efficiency, isolated DC/DC
converter. Neither heat sink nor airflow is
required when the unit operates at ambient
temperature of 25°C. The unit has basic control,
output adjustment and protection functions.
Input (Pin 2, Pin 3)
Input power Vin(+) must be connected to Positive
input pin 3; Input power Vin(-) must be connected
to Negative input pin2.
Output (Pin 4, Pin 6)
Fig 1. Recommended ON/OFF circuit configuration
Output power Vout(+) must be connected to
Positive output pin 4; Output power Vout(-) must
be connected to Negative output pin6.
Remote Sense
Output Common ( Pin 5)
Trim Pin
The unit does NOT have remote sense pins.
Pin 5 is Vout(+) and Vout(-) common pin.
S15-48-15D Brick does not have Trim pin.
ON/OFF (Pin 1)
Permits the user to maintain unit On/Off, in order
to properly sequence different power supplies
and reduce power consumption during the
standby condition. On/Off pin(pin 1) is referenced
to Vin-.
Pin 1 is the "Enable" pin, connecting a TTL
compatible pin. A TTL control signal to this pin,
according to the specification, turns the unit on or
off.
The positive logic unit turns on when the pin is at
logic high or open, and turns off at logic low.
The negative logic unit turns on when the pin is at
logic low, and turns off at logic high state.
Typical ON/OFF connection is shown in Fig 1.

Protection Features
Safety Requirements (SR)
Input under voltage lockout (UVL)
The unit meets UL/CSA/TUV safety requirements
per UL60950, TUV EN60950 and CSA C22.2
No.60950-00.
Basic insulation is provided
between input and output.
The input voltage must be at least 35V for the
unit to turn on. Once the unit has been turned on,
it will shut off when the input voltage drops below
34V.
Output Over-Current Protection (OCP)
The unit is protected against over current or short
circuit on the output. When sensing an over
current condition, the unit will enter constant
current operation and reduce the output voltage.
Upon short-circuit condition, the unit will shut
down.
After over-current or short circuit condition is
removed, the unit will resume normal operation
automatically.
Output Over Voltage Protection (OVP)
This unit does NOT have OVP function.
Over Temperature Protection (OTP)
This unit does NOT have OTP function.
Application Considerations
Input source Impedance
The unit has been designed to be stable with no
external capacitor when used in a low inductance
input and output circuit.
Caution:
The unit does NOT have a fuse inside. The safety
agencies require an external normal-blow fuse to be
used at the input side to achieve maximum safety. The
recommended fuse rating is 2A/100V.
If the input source is non-SELV (ELV or a
hazardous voltage greater than 60 Vdc and less
than or equal to 75 Vdc), for the unit output to be
considered meeting the requirements of safety
extra low voltage (SELV), all of the following must
be met:
• The input source is to be provided with
reinforced insulation from any hazardous
voltage, including the ac main.
• The input pins of the unit are not operator
accessible.
• For the whole system, for safety agencies
requirements, and for the combination of
the unit input side (primary side) and the
output side (secondary side), verify that
under a single fault, hazardous voltages
do not appear at the unit output side
(secondary side).
• Never ground either of the input pins of
the unit without grounding one of the
output pins. This may allow a non-SELV
voltage to appear between the output pin
and ground.
However in many applications, the inductance
with the distribution from the power source to the
input of the unit can affect the stability of the unit.
An external capacitor will improve the stability of
the unit. Also in many applications, the user has
to use decoupling capacitors at the output load,
to ensure the hold up time for the load.

Electromagnetic Compatibility (EMC)
Input Transient Withstand (ITW)
The unit’s conducted emission meets the
requirement of EN55022 Class B Specifications,
so the external input filter is needed unless a
stricter conducted EMI/EMC limitation is required
to satisfy or user has its own requirement on the
input.
The unit can withstand input transient voltage with
100V/100ms pulse and never be damaged.
