The TPS6211x devices are a family of low-noise synchronous step-down dc-dc converters that are ideally suited for systems powered from a 2-cell Li-ion battery or from a 12-V or 15-V rail. They feature high efficiency, adjustable output voltage range, synchronous rectification, synchronizable to external clock signal, and more.
The TPS6211x family are low‑noise synchronous step‑down DC‑DC converters designed for 2‑cell Li‑ion, 12 V or 15 V sources. They feature adjustable output from 1.2 V to 16 V or fixed 3.3 V/5 V versions, up to 1.5 A output current, and up to 95 % efficiency. The devices include integrated P‑channel MOSFETs, over‑temperature and over‑current protection, and can be synchronized to an external clock up to 1.4 MHz.
The datasheet provides detailed electrical characteristics, absolute maximum ratings, pin assignments, functional block diagram, typical performance graphs, mechanical dimensions for the 16‑pin QFN package, and handling guidelines for ESD‑sensitive devices.
