资 源 简 介
The TPS6275x device is a highly efficient synchronous step down dc-dc converter opTImized for USB powered portable applicaTIons. It can provide up to 1300mA average input current and is ideal for applicaTIons connected to a USB host.
With an input voltage range of 2.9 V to 6.0V, the device supports batteries with extended voltage range and is ideal for powering USB applicaTIons where USB compliance is required.
The TPS62750 operates at 2.25-MHz fixed switching frequency and enters Power Save Mode operation at light load currents to maintain high efficiency over the entire load current range. The TPS62751 operates in Forced PWM mode allowing use in applications that are noise sensitive. An output discharge allows the load to discharge in shutdown.
