The TPS6300x series is a high-efficiency single-inductor buck-boost converter with 1.8-A switches, an input voltage range of 1.8V to 5.5V, and a fixed output voltage of 3.3V. The output current can be as high as 1200 mA. This series of products is suitable for products powered by two or three alkaline, nickel-cadmium or nickel-metal hydride batteries or a single lithium-ion or lithium-polymer battery.
The TPS63000, TPS63001 and TPS63002 devices provide a high‑efficiency buck‑boost power solution for battery‑powered products. They operate from 1.8 V to 5.5 V input, deliver up to 1200 mA in step‑down mode and 800 mA in boost mode, and feature automatic mode transition, power‑save operation, and over‑temperature protection.
The devices are offered in a compact 3 mm × 3 mm QFN‑10 (PowerPAD) package and include detailed electrical characteristics, pin assignments, and layout guidelines. The datasheet includes efficiency graphs, maximum output current curves, and land‑pattern recommendations for board design.
