Figure 3 - TypicalApplication.
Inhibit/Enable Input
The Inhibit/Enable function allows the ON/OFF
logiccontrol of the module.
The converter is ON (Enable) when the voltage
applied to pin 2 (EN.) and referred to pin 1 (GND
IN) is lower than0.8V (TTL, CMOS, open collector
compatiblelevel).
The converter is OFF (Inhibit)when pin 2 is uncon-
nectedor thevoltageappliedis in the rangeof1.2V
to +Vin. Maximum sinking current is 1mA.
Module Protection
The module is protected against occasional and
permanent short-circuits of the output pins to
ground,as wellas againstoutput current overload.
The main output (+5.1V) uses a foldback current
limiting; the outputcurrent decreases with increas-
ing overload, reaching a minimum at short-circuit
condition.
This solution minimizes internal power dissipation.
The auxiliary outputs(
±
12V or
±
15V) use a current
limiting protectioncircuitry.
Thermal characteristics
SometimestheGS-R51212Sand GS-R51515Sre-
quire an external heat-sinkdepending on both op-
erating temperatureconditionsand power.
Before entering into calculations details, some ba-
sic conceptswill be explainedto betterunderstand
the problem.
The thermal resistance between two points is rep-
resented by their temperaturedifferencein front of
a specifieddissipatedpower,and it is expressed in
Degree Centigradeper Watt (
°
C/W).
For the modules the thermal resistance case to
ambient is 7.5
°
C/W. This means that an internal
powerdissipationof1Wwillbringthecasetempera-
ture at 7.5
°
C abovethe ambienttemperature.
The maximum case temperatureis 85
°
C.
Let’s supposeto have a GS-R51515Sthat delivers
the maximumoutputpower of31.4Wat anambient
temperatureof 40
°
C.
