Notes:
Typical Connection
1. The specified maximum capacitive load is for each output.
2. When measuring output ripple, it is recommended that an external 0.47 µF ceramic
capacitor be placed in parallel from the +VOUT pin to the -VOUT pin for single output models,
or from each output to common for dual output models.
3. Transient recovery is measured to within a 1% error band for a load step change
of 25%.
4. Output overload protection is provided by a Hiccup circuit with auto-recovery.
5. Output short circuit protection is provided by a Hiccup circuit with auto-recovery.
6. These converters are specified for operation without external components. However,
in some applications the addition of input/output capacitors, as shown in the typical
connection diagram at right, will enhance stability and reduce output ripple. This simple
connection includes a low ESR (<1Ω at 100 kHz) capacitor connected across the
input. It is recommended that a 2.2 µF be used. To improve the output ripple
performance, a 3.3 µF is connected across the output. For dual output units, a 3.3
µF capacitor should be connected from each output to common. For applications where
the circuit must meet or exceed EN 61000-4-4 (5), refer to the note under the typical
connection diagram.
Notes:
To meet the specified EN 61000-4-4 and EN 61000-4-5 limits, an external capaci-
tor must be connected across the input pins of the module (C1). A 220 µF/100V
capacitor is recommended. This capacitor should be mounted as close to the module as
possible.
7. Operation at no load will not damage these units,however,they may not meet all specifica-
tions.
8. 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.
