Introduction

AI Translation

The TPS62743 is a high efficiency step down converter with ultra low quiescent current of typical 360 nA. The device is optimized to operate with a 2.2 μH inductor and 10 μF output capacitor. The device uses DCS-Control™ and operates with a typical switching frequency of 1.2 MHz. In Power Save Mode the device extends the light load efficiency down to a load current range of 10 μA and below. TPS62743 provides an output current of 300 mA. Once started the device operates down to an input voltage range of 2.0 V. This allows to operate the device directly from a single Li - MnO₂ coin cell. The TPS62743 provides 8 programmable output voltages between 1.2V and 3.3V selectable by three selection pins. The TPS62743 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.
