Description: 800mA Buck Converter

Features

* 92% Efficient Synchronous Operation 2.7V to 5.5V Input Voltage Range VOUT Range from 0.4V to 3.4V (or VIN) Up to 800mA Output Current 20µs Step Response 30µs Bypass Transition Time 50mΩ Integrated Bypass FET with Controlle

Applications

* It provides up to 800mA of output current over an input voltage range of 2.7V to 5.5V. The output voltage can be dynamically adjusted from 0.4V up to 3.4V, proportional to an analog input voltage ranging from 0.2V to 1.7V provided by an external DAC. This allows supplying the RFPA with the voltage
