FEATURES DESCRIPTIONS Vi(+) Vo(+) Over-Current Protection Sense(+) The modules include an internal output over-current ON/OFF protection circuit, which will endure current limiting for an unlimited duration during output overload. If the Sense(-) output current exceeds the OCP set point, the modules will automatically shut down (hiccup mode). Vi(-) Vo(-) The modules will try to restart after shutdown. If the overload condition still exists, the module will shut down Figure 16:

FEATURES DESCRIPTIONS (CON.) Output Voltage Adjustment (TRIM) To increase or decrease the output voltage set point, the modules may be connected with an external resistor between the TRIM pin and either the SENSE(+) or SENSE(-). The TRIM pin should be left open if this feature is not used.
