Load Disconnect for the TPS61170
Many boost converters have an external rectifier diode. The input voltage of the TPS61170 main boost converter is connected to the output voltage when the device is
disabled. Due to the direct pass from the input to the output, the input supply is not isolated from the output voltage when the IC is disabled. This application report describes how to use a PMOS transistor to disconnect the boost converter’s input voltage from the output voltage (known as load disconnect or input to output isolation) when the device is disabled.
