General Description
The BD90571EFJ-C is a synchronous rectification type step-down DC/DC converter with a 2.25MHz fixed frequency that operates in with an input voltage range of 2.69V-5.5V. It has an integrated feedback resistor that supplies a fixed output voltage of 1.2V and a phase compensation constant. Applications can be created with a minimum of three external components. Moreover, the integrated Pch and Nch output MOSFET can supply a maximum output current of 1A.
