产品介绍 说明
The TPS6269x device is a high-frequency synchronous step-down dc-dc converter optimized for battery-powered portable applications. Intended for low-power applications, the TPS6269x supports up to 600-mA load current, and allows the use of low cost chip inductor and capacitors. The device is ideal for mobile phones and similar portable applications powered by a single-cell Li-Ion battery. Different fixed voltage output versions are available from 2.2V to 2.9V. The TPS6269x operates at a regulated 4-MHz switching frequency and enters the power-save mode operation at light load currents to maintain high efficiency over the entire load current range. The PFM mode extends the battery life by reducing the quiescent current to 19µA (typ) during light load operation. 特性
