This document introduces TPS61010, TPS61011, TPS61012, TPS61013, TPS61014, TPS61015, TPS61016 these high efficiency, 1-cell and 2-cell boost converters. These devices use an integrated synchronous rectifier for highest power conversion efficiency (>95%), support output current of 200 mA with a supply voltage of only 0.9 V. The converter starts up into a full load with a supply voltage of only 0.9 V and stays in operation with supply voltages down to 0.8 V. Since it uses a built-in synchronous rectifier, no external Schottky diode is required, thus the system efficiency is improved. The current through the switch is limited to a maximum of 50 µA.
The TPS61010‑TPS61016 family provides high‑efficiency boost conversion for single‑cell or dual‑cell battery‑powered products such as audio players, pagers, medical devices, remote controls and wireless headsets. Integrated features include a synchronous rectifier, power‑save mode, autodischarge, low‑battery detection and an antiringing switch, all in a micro‑small 10‑pin MSOP or 3 mm×3 mm QFN package.
The devices operate from an input voltage as low as 0.9 V (full‑load start‑up) and continue to run down to 0.8 V. Output voltage can be fixed or adjusted between 1.5 V and 3.3 V, delivering up to 200 mA with a quiescent current below 50 µA. Detailed electrical characteristics, absolute maximum ratings and mechanical data are provided for design reference.
