TPS62743YFPT 编带
The is a Step-down Converter with ultra-low quiescent current of typical 360nA. It is optimized to operate with a 2.2µH inductor and 10µF output capacitor. It uses DCS-Control™ and operates with a typical switching frequency of 1.2MHz. In power save mode the device extends the light load efficiency down to a load current range of 10µA and below. It provides an output current of 300mA. Once started the device operates down to an input voltage range of 2V. This allows to operate the device directly from a single Li-MnO2 coin cell. It provides 8 programmable output voltages between 1.2 and 3.3V selectable by three selection pins. It is optimized to provide a low output voltage ripple and low noise using a small output capacitor. Once the input voltage comes close to the output voltage the device enters the no ripple 100% mode to prevent an increase of output ripple voltage. In this operation mode the device stops switching and turns the high side MOSFET switch on.
