Notes:

1. The input voltage should not exceed the max value given in the table above. Damage to the

unit could occur.

2. Transient recovery is measured to within a 1% error band for a 75-100% load change.

3. To meet the requirements of EN 55022, external filtering components are required on the input.

A sample circuit is shown in the typical connection diagram below.

4. To meet the requirements of EN 61000-4-4 and EN 61000-4-5, external components are

required on the input. A sample circuit is shown in the typical connection diagram below.

5. Operation at no-load will not damage these units. However, they may not meet all specifica-

tions. It is not recommended that the units be operated with a load under 5%.

6. 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.

Connection Notes:

1. Typical component values are given in the table at right.

2. The trace (or wire) between the DC/DC and the driver circuit

should be as short as possible.

3. External filter capacitors should be mounted as close to the

unit as possible.

4. To ensure peak gate current, these capacitors should have a

5. If the output capacitance is increased to meet ap-

plication requirements, caution must be taken not to

exceed the maximum capacitive load capability of the

unit (see table above).

6. The average output power of the driver circuit must

be lower than output power of the DC/DC.

7. Filter and surge protection modules may be available

form MicroPower Direct. Please contact the factory

for more information.
