Notes:
1. When measuring output ripple, it is recommended that an external ceramic capacitor
(approx 10 µF) be placed from the +VOUT to the -VOUT pins.
2. Transient recovery is measured to within a 1% error band for a load step change of 25%.
3. Short circuit protection is provided by a “hiccup mode” circuit.
4. The maximum control current at the on/off pin (pin 6) during a logic high is 50 µA. The
maximum control current to the on/off pin at logic low (-0.7V to 0.8V) is 1 mA. If the on/
off pin is left open, the unit operates. If it is grounded, the unit will shut off.
5. These units should not be operated with a load under 5% of full load. Operation at no-load
will not damage the unit, but they may not meet all specifications.
6. These units should not be operated over +85°C. Exceeding +85°C may damage the unit.
7. It is recommended that a fuse be used on the input of a power supply for protection. See
the Model Selection table above for the correct rating.

External Trim Notes:
On single output units, an external resistor can be used to adjust the converter
output up/down by about 10%. The connection is shown in the diagram at left. The
required resistor value is calculated by the formulas:
Trim UP = RTRIM = A $-R2 - R3
R2 A
Trim Down = RTRIM = A $-R1 - R3
R1 A
Where A =
VREF
$ R1
VTRIM - VREF
Where A = VTRIM VREF $ R2
VREF
Where RTRIM = Value of the external trim resistor
VTRIM = Amount of voltage adjustment required
The value of R1, R2, R3 and VREF are given in the table below.

3. All units will meet class B with the addition of the MDCFM-40U (or a similar
discrete filter circuit) as shown in the circuit/board layout diagrams below.
Contact the factory for more information.
4. To meet the requirements of EN 61000-4-4 (±2 kV), external components are
needed. This can be done discretely, or with the addition of the MDCFM-40U.
Contact the factory for more information.
5. To meet the requirements of EN 61000-4-5 (±2 kV/±4 kV), external components are needed. This can be done discretely, or with the addition of the

Typical Connection
The diagram above illustrates a typical connection of the MR1511S series The
MDCFM-40U filter module is used to make the circuit compliant with input
surge and EMC standards EN 55022, EN61000 and EN 50155. This can also be
accomplished by using external filter components as shown in the board layout
drawing below. Some notes on these components are:
1. It is recommended that an external fuse be used. The recommended fuse is
shown in the model chart on page 2.
2. An external MOV is recommended on the input to protect the unit in the event
of a surge. A recommended value is given in the table at right.
3. An external TVS is recommended on the input to protect the unit in the event
of a voltage spike. A recommended value is given in the table at right.
4. The output filtering capacitor (C3) is a high frequency, low resistance electrolytic
capacitor. Care must be taken in choosing this capacitor not to exceed the
capacitive load specification for the unit. Voltage derating of capacitors should
be 80% or above.
