PRODUCTION DATA
The OCP level is chosen such that it is 30% above the maximum load current, ICC(max). In the equation, here RCS is the current sense resistor.Equation 4. IVALLEY is the load current less half the ripple.
Set the OCP threshold level just greater than the calculated IVALLEY for the required OCP level. Equation 4. In this design, the minimum required OCP is 65A. Therefore, an OCP selection resistor of 56k is chosen to meet the requirement.
Table 8-4 shows the minimum OCP level for all the selection resistors.
