During soft start, the device forces diode emulation while the SS pin voltage is less than 1.5 V. When the SS pin is greater than 1.5 V, the device reduces the zero current detection (ZCD) threshold down to –145 mV. The peak-to-peak inductor current must satisfy Equation 14 for a proper FPWM operation at no load.
