Voltage Margining
Bel Power, Inc. , a subsidiary of Bel Fuse, Inc.
Output voltage margining can be implemented in the SLIN-06F2Ax modules by connecting a resistor, Rmargin-up
from the Trim pin to the ground pin for margining-up the output voltage and by connecting a resistor, Rmargin-down
from the Trim pin to output pin for margining-down.

Circuit Configuration for margining Output voltage
Monotonic Start-up and Shutdown
The SLIN-06F2Ax modules have monotonic start-up and shutdown behavior for any combination of rated input
voltage, output current and operating temperature range.
Startup into Pre-biased Output
The SLIN-06F2Ax modules can start into a prebiased output as long as the prebias voltage is 0.5V less than the
set output voltage.
