TPS62056 概述

The TPS62056 devices is a high-efficiency synchronous step-down dc/dc converter ideally suited for systems powered from a 1-cell or 2-cell Li-Ion battery or from a 3-cell to 5-cell NiCd, NiMH, or alkaline battery.

The TPS62056 is a synchronous PWM converter with integrated N-channel and P-channel power MOSFET switches. Operating frequency is typically 850 kHz, allowing the use of small inductor and capacitor values. The TPS62056 can be synchronized to an external clock signal in the range of 600 kHz to 1.
