Technical Reference Notes  
AEO_ALO04/12/20/25x48 Series  
(Single Output 8th Brick)  
Basic Operation and Features  
INPUT UNDER VOLTAGE LOCKOUT  
To prevent any instability to the converter, which may affect the end system, the converter have been designed to turn-on once  
V
IN is in the voltage range of 33 to 36VDC. Likewise, it has also been programmed to turn-off when VIN drops down to 31 to  
34VDC  
OUTPUT VOLTAGE ADJUST/TRIM  
The converter comes with a TRIM pin (PIN 6), which is used to adjust the output by as much as 90% to 110% of its set point.  
This is achieved by connecting an external resistor as described below.  
To INCREASE the output, external Radj_up resistor  
-Vout  
should be connected between TRIM PIN (Pin6) and  
+SENSE PIN (Pin 7). Please refer to Equation (1) for the  
required external resistance and output adjust  
relationship.
