• Manufacturer Part Number: sfs13ze-m6
• Description: Sfs Dc-dc Series
• Manufacturer: Power-One

Typical Application
This series of converters does not require any external
components for proper operation.
distribution of the input voltage to the converter
contains significant inductance, a capacitor across the
input terminals may be required to stabilize the input
voltage.
ceramic capacitor is recommended for this purpose.
For output decoupling it is recommended to connect a
1 μF ceramic capacitor directly across the output pins
of the converter (illustrated as follows).
Shutdown Feature
The remote control pin functions as a normal soft
shutdown.
positive logic, when the remote control pin is pulled
low, the output is turned off and the unit goes into a
very low input power mode.
An open collector switch is recommended to control
the voltage between the remote control pin and the -
Vin pin of the converter. The remote control pin is
pulled up internally, so no external voltage source is
required. The user should avoid connecting a resistor
between the remote control pin and the +Vin pin.
The user must take care to ensure that the pin
reference for the control is connected close to the -Vin
pin. The control signal must not be referenced ahead
of EMI filtering, or remotely from the unit. If the remote
control pin is not used, it can be left floating.

Thermal Considerations
The converter is designed for natural or forced
convection cooling. The output power of the converter
is limited by the maximum case temperature (T

Output Current Limiting
When the output is overloaded above the maximum
output current rating, the voltage will start to reduce to
maintain the output power to a safe level. In a
condition of high overload or short-circuit where the
output voltage is pulled below approximately 30% of
V
operation. Under this condition the unit will attempt to
restart, approximately every 20 ms until the overload
has cleared.
Voltage Sense Description
The voltage sense feature compensates for voltage
drops that may occur at the point of load due to PCB
tracks or other losses. Pin 3 and pin 16 are used to
sense the output voltage at point of load.
If the sense feature is not used, it is recommended to
connect pin 3 to pins 1 & 2 and pin 16 to pins 17 & 18.
Note:
When the output voltage is sensed remotely at the
load, the output power from the converter must not
exceed maximum rating.

pins) by the output current.
