Adjustable Undervoltage Lockout Circuit Used in TPS61022 and TPS61023

TI's TPS61022 and TPS61023 boost converters can operate down to a 0.4-V input voltage after the devices start up. However, a higher undervoltage lockout value is required in some applications. This application report proposes an external circuit that can adjust the undervoltage lockout voltage between 0.4 V and 1.7 V.
