Working Principle

The TPS62082DSGR is a synchronous buck-boost power converter that combines a buck and a boost converter using a single high-side and a low side FET (field effect transistor) and integrated synchronous rectifier. The output voltage of the regulator is precisely regulated as a function of the feedback voltage, which is generated from a resistive voltage divider connected to the output and the feedback pin. The connected buck-boost converter can maintain a fixed voltage output at all times, eliminating the need for an additional controller.

The TPS62082DSGR also enables pre-bias startup capability, allowing the part to start up correctly even if the input voltage is lower than the desired output voltage. The device includes a programmable soft-start feature to prevent overshoot at startup and a slew rate control to limit the output current. The integrated FETs are capable of switching up to 6A of output current.

The TPS62082DSGR has a range of features designed to improve battery life and reduce system power consumption. These features include adjustable input current limit, battery pre-charge, low-battery and over-temperature monitoring, and current- sharing for multi-cell battery stacks.
