TPS62207 概述

The TPS62207 is a high-efficiency synchronous step-down converter ideally suited for portable systems powered by 1-cell Li-Ion or 3-cell NiMH/NiCd batteries. The TPS62207 is also suitable to operate from a standard 3.3-V or 5-V voltage rail.

With an output voltage range of 6 V down to 0.7 V and up to 300 mA output current, the TPS62207 is ideal to power low voltage DSPs and processors used in PDAs, pocket PCs, and smart phones. Under nominal load current, the TPS62207 operates with a fixed switching frequency of typically 1 MHz.
