When skip mode is selected as the light load switching mode and SS is greater than 1.5 V, the device enters sleep mode if the low-side driver skips switching for 16 consecutive cycles. Once the device enters sleep mode, the device cannot re-enter active mode during 8-μs minimum sleep time. During sleep mode, the device stops the internal oscillator to reduce the operating current, disables UVLO comparator, disables the error amplifier, and parks the COMP pin at 0.25 V. The device re-enters active mode if the VOUT pin voltage falls down below the wake up threshold (V_WAKE), which is 1.1% lower than V_OUT-REG.
