This document describes the features and characteristics of the TPS6120x series products, including low input voltage, synchronous boost converter, high efficiency, overtemperature protection, etc. These products are suitable for products powered by single-cell, two-cell, or three-cell alkaline, NiCd or NiMH, or one-cell Li-Ion or Li-polymer battery.
The TPS6120x family provides low‑input voltage synchronous boost conversion with up to 1.3 A switch capability. It supports single‑cell, two‑cell, or three‑cell battery sources as well as fuel‑cell or solar‑cell power, offering programmable or fixed output voltages from 1.8 V to 5.5 V.
The document includes functional block diagrams, pin assignments, electrical characteristics, typical performance graphs, thermal pad information and absolute maximum ratings. It is intended for designers needing efficient power‑management solutions in portable audio, PDAs, cellular phones and medical devices.
