MP4568 - MPS

MP4568 Step-Down Converter

The MP4568 is a high-frequency, step-down, switching regulator with integrated highside/low-side, high-voltage power MOSFETs. It provides a highly efficient output of up to 100mA. 60V rated MOSFETs and 4.5V to 45V operation range accommodates a variety of step-down applications in automotive input environment. A 5μA shutdown mode quiescent current allows use.
