MPQ4346 Ultra-Low Quiescent Current Synchronous Step-Down Converter

The MPQ4346/4346J is a configurablefrequency (350kHz to 2.5MHz), synchronous, step-down switching regulator with integrated internal high-side and low-side power MOSFETs (HS-FET and LS-FET, respectively). It provides 3A highly efficient output with fixed-frequency, zero-delay PWM control for near op.
