Description
The RP75-SB Series has been specifically designed for low voltage silicon applications. A wide input vol-
tage range, output voltage trim and sense inputs are all standard features. The converters also benefit
from comprehensive over-current, over-voltage and over-temperature protection.
The RP75-SB is ideally suited to telecom, network and industrial applications.
Notes:
1. Maximum output deviation is 10% inclusive of remote sense. If remote sense is not being used,
the +Vsense should be connected to its corresponding +Vout
2. The pin voltage is referenced to negative input.
3. Heat sink is optional and P/N: 7G-0021, 7G-0022, 7G-0023, 7G-0024.
4. The RP75-SB meets level A and level B conducted emissions only with external components connected before
the input pin to the converter.
5. Typical value at nominal input voltage and full load.
6. BASEPLATE GROUNDING : Base-plate should be grounded at one of the four screw bolts prior to operation.
