6.4.2 Normal Mode and Skip Mode Operation

The TPS60150 device has skip mode operation as shown in Figure 6-3. The TPS60150 device enters skip mode if the output voltage reaches 5V +0.1V and the load current is less than 8mA (typical). In skip mode, the TPS60150 device disables the oscillator and decreases the prebias current of the output stage to reduce the power consumption. Once the output voltage dips less than the threshold voltage of 5V +0.1V, the TPS60150 device begins switching to increase output voltage until the output reaches 5V +0.1V. When the output voltage dips less than 5V, the TPS60150 device returns to normal pulse width modulation (PWM) mode; thereby reenabling the oscillator and increasing the prebias current of the output stage to supply output current.

The skip threshold voltage and current depend on input voltage and output current conditions.
