TPS6300x is a high-efficiency single inductor buck-boost converter with up to 1200mA output current and a working voltage range of 1.8V~5.5V.
The TPS63000/01/02 family provides a high‑efficiency buck‑boost solution for battery‑powered products. Features include up to 96% efficiency, 1.8 A switch current, input range 1.8‑5.5 V, and selectable output voltages from 1.2 V to 5.5 V. The devices are offered in a compact 3 mm × 3 mm QFN‑10 package and include power‑save and over‑temperature protection modes.
Electrical characteristics such as oscillator frequency (1.25‑1.5 MHz), switch current limit (≈1.8 A), and detailed pin assignments are provided. Recommended operating conditions, absolute maximum ratings, and layout guidelines are also included to aid designers in implementing the converter in portable audio players, PDAs, cellular phones, and LED lighting applications.
