7.3.7 Overvoltage Protection

TPS61099x has an output overvoltage protection (OVP) to protect the device in case that the external feedback resistor divider is wrongly populated. When the output voltage of the TPS61099 exceeds the OVP threshold of 5.8V, the device stops switching. After the output voltage falls 0.1V below the OVP threshold, the device starts operating again.
