Extending Soft Start Time in TPS6107x Family of Boost

In battery-powered equipment, extending the soft start time can be crucial to a glitch-free start-up. Especially toward the end of a battery's life, the voltage drop and increasing impedance of the battery from excessive inrush current into the power supply can be a problem. This application report demonstrates a simple circuit that extends the soft start time and reduces the inrush current on the TPS6107x family of boost converters.
