Output voltage can be adjusted by connecting a single resistor between the TRIM and GND pins of the module.To calculate the value of the
resistor
Rtrim
for a particular output voltage
Vo,
use the following equation: in
Table1
OSR03-12S3P3: When use negative output application and |Vo| trim up >3.3V, the Output Current maxmum is 1.5A
OSR03-12S3P3 : When Vo,set < 0.9V, the input voltage range is 4.5V to 9V.
CAUTION:
This power module is not internally fused. An input line fuse must always be used.
