APPLICATION NOTES
1. Input filtering
ToꢀreduceꢀtheꢀreflectedꢀrippleꢀcurrentꢀandꢀminimizeꢀEMI,ꢀespeciallyꢀwhenꢀtheꢀconverterꢀinputꢀisꢀmoreꢀthanꢀ2”ꢀawayꢀfromꢀtheꢀDCꢀ
source,ꢀitꢀisꢀrecommendedꢀtoꢀconnectꢀaꢀlowꢀESRꢀelectrolyticꢀcapacitorꢀbetweenꢀVinꢀandꢀGnd.ꢀTheꢀvaluesꢀsuggestedꢀareꢀasꢀshownꢀinꢀ
Tableꢀ1.ꢀIfꢀadditionalꢀfilteringꢀisꢀrequired,ꢀtheꢀcapacitanceꢀmayꢀbeꢀincreased,ꢀorꢀexpandedꢀtoꢀanꢀLCꢀnetworkꢀasꢀshownꢀinꢀFigureꢀ1.

3. Output filtering
An output capacitor as shown in Table 2 may be used to reduce output ripples and noise. requirements as shown in Table 2. Output

4. Minimum loading
The converter needs a minimum of 10% loading to maintain output regulation. Operation under no-load conditions will not cause
immediateꢀdamagesꢀbutꢀmayꢀreduceꢀreliability,ꢀandꢀcauseꢀperformanceꢀnotꢀtoꢀmeetꢀspecifications.
5. Protection
Theꢀconverterꢀhasꢀminimalꢀprotectionꢀagainstꢀinputꢀover-voltageꢀorꢀoutputꢀover-load,ꢀandꢀmayꢀbeꢀpermanentlyꢀdamagedꢀifꢀexposedꢀtoꢀ
these conditions. An input clamping device can be used for input voltage limiting. An input fuse or an output fuse can also be used to
protect against over-loading.
6. Unregulated input
Asꢀfixedꢀinputꢀconverters,ꢀthisꢀseriesꢀcanꢀacceptꢀvoltagesꢀwithinꢀaꢀlimitedꢀrangeꢀofꢀtheꢀnominalꢀinput.ꢀOtherwiseꢀtheꢀconverterꢀmayꢀnotꢀ
functionꢀproperlyꢀorꢀmayꢀbeꢀdamaged.ꢀAnꢀoptionalꢀregulatorꢀcanꢀbeꢀusedꢀatꢀtheꢀinputꢀtoꢀbringꢀvoltageꢀwithinꢀregulation,ꢀasꢀshownꢀinꢀ

7. Overload protection
Underꢀnormalꢀoperatingꢀconditions,ꢀtheꢀoutputꢀcircuitꢀofꢀtheseꢀproductsꢀhasꢀnoꢀprotectionꢀagainstꢀover-currentꢀandꢀshort-circuits.ꢀTheꢀ
simplest method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit.
Whenꢀtheꢀenvironmentꢀtemperatureꢀisꢀhigherꢀthanꢀ70°C,ꢀtheꢀproductꢀoutputꢀpowerꢀshouldꢀbeꢀlessꢀthenꢀ60%ꢀofꢀtheꢀratedꢀpower.
Note:ꢀ
Allꢀspecificationsꢀmeasuredꢀatꢀ25°C,ꢀhumidityꢀ<75%,ꢀnominalꢀinputꢀvoltage,ꢀandꢀfullꢀloadꢀunlessꢀotherwiseꢀnoted.
