6.3.4 Current Limit
The buck controllers (BUCK1, BUCK2, and BUCK6) have inductor-valley current-limit architecture and the current limit is programmable by an external resistor at the ILIMx pin. Equation 1 shows the calculation for a desired resistor value, depending on specific application conditions. The ILIMREF current is the current source out of the ILIMx pin that is typically 50 μA, and RDSON is the maximum channel resistance of the low-side FET. The scaling factor is 1.3 to consider all errors and temperature variations of RDSON, ILIMREF, and RILIM. Finally, 8 is another scaling factor associated with the ILIMREF current.
Equation 1. 
where
- ILIM is the target current limit. An appropriate margin must be allowed when determining the value of ILIM from the maximum DC load current of the output.
- Iripple(min) is the minimum peak-to-peak inductor ripple current for a given output voltage.
Equation 2. 
where
- Lmax is the maximum inductance.
- fsw(max) is the maximum switching frequency.
- VIN(MIN) is the minimum input voltage to the external power stage.
The inductor of the buck converter limits the peak current. This current limiting is done on a cycle-by-cycle basis to the current limit (IIND_LIM), which is specified in Section 5.8.
