Notes:
1. The RP40 G-series requires a minimum of 10% loading on the output to maintain specified
regulation. Operation under no-load condition will not damage these devices, however
they may not meet all listed specification.
2. Simulated source impedance of 12uH. 12uH inductor in series with +Vin.
3. The ON/OFF control pin voltage is referenced to negative input.
4. Maximum value at nominal input voltage and full load.
5. Typical value at nominal input voltage and full load.
6. It will compensate for up to 0.5V line drop voltage between converter and load.
If remote sense is not being used, the +sense should be connected to its corresponding
+OUTPUT and likewise the sense should be connected to its corresponding OUTPUT.
