The document describes the features and characteristics of the TPS6120x series products, including low input voltage synchronous boost converter, power save mode for improved efficiency at low output power, over 90% efficiency, overtemperature protection, automatic transition between boost mode and down conversion mode, etc.
The TPS6120x devices are low‑input voltage synchronous boost converters designed for battery‑powered products such as single‑cell, two‑cell, or three‑cell alkaline, NiCd, NiMH, Li‑ion or Li‑polymer batteries, as well as fuel‑cell and solar‑cell applications. They provide selectable output voltages from 1.8 V to 5.5 V, feature Power Save mode for high efficiency at light loads, and include protections like over‑temperature and short‑circuit protection.
The devices are supplied in a 3 mm × 3 mm 10‑pin QFN‑10 (PowerPAD) package, support up to 600 mA output current at 5 V, and have a quiescent current of less than 55 µA. Detailed electrical characteristics, pin assignments, functional block diagrams, typical performance curves, and layout guidelines are provided in the document.
