TPS62750的产品详情:

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.

The 10% accurate average input current limit can be programmed with an external resistor, allowing use in applications such as USB, where the current drawn from the bus must be limited to 500mA.

The TPS6275x allows the use of small inductors and capacitors to achieve a small solution size. The TPS6275x is available in a 2,5mm × 2,5mm 10-pin SON package.
