- If the ’CURR. LIMIT’ function (pin 8) is left open, the ICL decreases from 11.5 A(NOM) as VIN is decreased from 5V (Table 3).

- To increase the current limit above the nominal setting for any VIN and ICL combination, use the following formula:

- To maintain ICL at the 11.5 A setting, for commonly found VIN voltages, apply RINC value found in Table 4.
