Auxiliary Functions  
Depending upon the value of the required output voltage,  
the resistor shall be connected:  
Shutdown Function  
The outputs of the converters may be enabled or disabled by  
means of a logic signal (TTL, CMOS, etc.) applied to the shut-  
down pin. If this function is not required, the shut-down pin  
should be left open-circuit.

The control voltage range is 1.96 to 2.62 V and allows for  
adjustment in the range of Vo 80 to 105% of Vo nom  
As a standard feature, the single- and double-output models  
offer adjustable output voltage(s) by using the control input R  
or Trim. If the control input is left open-circuit, the output  
voltage is set to Vo nom. For output voltages Vo > Vo nom, the

Attempting to adjust the output below this range will cause  
the converter to shut down (hiccup mode).  
.
Single-output models with synchronous rectifier (G):  
Note: Applying an external control voltage >2.75 V may damage  
the converter.  
The R input is referenced to the secondary side of the  
converter. Adjustment of the output voltage is possible by  
means of an external resistor connected between the R pin  
and either Vo+ or Vo–.
