The TPS63802DLAR is a highly integrated synchronous buck-boost DC-DC converter designed to provide a regulated output voltage when the input voltage is either above, below, or equal to the desired output voltage. The device automatically transitions between buck and boost operating modes to maximize efficiency across a wide input range. It is optimized for battery-powered and portable electronic applications requiring high power conversion efficiency, low quiescent current, compact solution size, and stable operation under varying load conditions. The TPS63802DLAR is commonly used in wearable devices, IoT products, wireless modules, sensors, handheld electronics, and embedded systems.
