7.5.2 Programing the Boost Current Limit
The peak current drawn from the supply through the inductor is set solely by the REXT resistor. Note that this peak current limit is independent of the inductance value chosen, but the inductor should be capable of handling this programmed limit. The relationship of REXT to ILIM is approximated by Equation 2.
Equation 2. 
where K = 10500, VREF = 1.35 V, RINT = 60 Ω, and ILIM is the desired peak current limit through the inductor.
