Figure 24. Normal Mode and Skip Mode Operation
The TPS60151 has skip mode operation as shown in Figure 24. The TPS60151 enters skip mode if the output
voltage reaches 5V+0.1V and the load current is below 8mA (typ). In Skip Mode, the TPS60151 disables the
oscillator and decreases the pre-bias current of the output stage to reduce the power consumption. Once the
output voltage dips below threshold voltage, 5V+0.1V, the TPS60151 begins switching to increase output voltage
until the output reaches 5V+0.1V. When the output voltage dips below 5V, the TPS60151 returns to normal PWM
mode; thereby re-enabling the oscillator and increasing the pre_bias current of the output stage to supply output
current.
The skip threshold voltage and current depend on input voltage and output current conditions.
