The Texas Instruments TPS631000DRLR is an active buck-boost converter designed for high-power-density applications. It features a wide input voltage range from 1.6V to 5.5V, with a requirement for input voltage greater than 1.65V for start-up. The output voltage is adjustable, ranging from 1.2V to 5.3V.
This converter boasts a 1.5A output current capability and a 3A peak switch current. It offers high efficiency across the entire load range and a low typical quiescent current of 8µA, with a power save mode. Key electrical features include a fixed-frequency operation at 2MHz, adjustable output, remote on/off control, and synchronous rectification.
Designed for robust operation, the TPS631000DRLR includes overcurrent protection, short-circuit protection, overtemperature protection, and overvoltage protection. It also features a true shutdown function with load disconnect and integrated soft start. The device is housed in a compact SOT-583 package, measuring 2.1mm x 1.6mm, and requires minimal external components, such as a 1µH inductor and one 0805 output capacitor.
Its operating temperature range is -40°C to 125°C, making it suitable for various environmental conditions. The converter supports forward and reverse current operation and can start up into prebiased outputs. The seamless mode transition with low output ripple ensures stable power delivery.
