SENSE (+ or -)
The + or – S pins should be connected to the load to have a tight regulation.
The maximum voltage drop that can be compensated for is 10% of Vout.
Note that the overvoltage protection senses the output voltage directly at + Vout and – Vout pins.
Care must be taken to avoid that the voltage at the output terminals + Vout and –Vout pins exceeds 1.98.
THERMAL CONSIDERATIONS
The module is provided with thermal protection that prevents the hot spot on the PCB from exceeding 125°C.
Depending on the air flow rate and the ambient temperature the maximum current reachable when the thermal protection
kicks in is shown in Figure 11-12-13-14.
OVERCURRENT PROTECTION
The overcurrent limit inception is typically at 110% of the rated output current. When this limit is exceeded the output
voltage decreases.
A further current increase will trigger the hiccup protection.
The behavior of the converter when the output is short circuited is shown in Figure 5.
