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.

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
applicationstheadditionofinput/outputcapacitors,asshowninthetypicalconnectiondiagram
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 3.3 µF be used for 12V input models and a 2.2 µF be used for 24V & 48V input
units. 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.
