7.4.5.3.3 Snooze Mode

The TPS61094 integrates Snooze mode to decrease quiescent current. If the load current is reduced further, the boost converter enters into Snooze mode. In Snooze mode, the boost converter ramps up the output voltage with several switching cycles. Once the output voltage exceeds a setting threshold, the device stops switching and goes into a sleep status. In sleep status, the device consumes less quiescent current. It resumes switching when the output voltage is below the setting threshold. It exits Burst mode when the output current can no longer be supported in this mode. Refer to Figure 7-7 for Burst mode operation details.
