Description
The BBS10N48P3V3 series power modules are sixteenth-brick DC/DC converters that provide high efficiency single output. It
can operate from 36Vdc to 75Vdc input and 3.3Vdc/10A output. The output can be trimmed from -10% to +10% of nominal
output voltage. The remote control option is negative logic. The converter turns on when the REM pins are at logic low and turns
off when it is at logic high or left open. The output voltage trim option is positive. The output voltage will increase when the TRIM
pin is connected to “+SENSE” and decrease when connected to “-SENSE”.

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.
