Description
The BBS5N48P14A series are sixteenth-brick DC/DC converters that provide high efficiency single output. It can operate from
36V to 75V input and 14V/5A output. The output can be trimmed from -10% to +10% of nominal output voltage. The remote
control options are negative logic. The converter turns on when the REM pins are at logic low and turns off when they are at
logic high or left open. The output voltage trim options are positive. The output voltage will increase when the TRIM pins are
connected to “+S” and decrease when connected to “-S”.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress
ratings only, functional operation of the device is not implied at these or any other conditions in excess of those given in the
operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect the
device reliability.
