MPQ4346J converter equivalent, ultra-low quiescent current synchronous step-down converter.
* Designed for Automotive Applications: o Survives 42V Load Dump o Supports 3.1V Cold Crank o Low-Dropout Mode o 3A Continuous Output Current (IOUT) o Continuous Oper.
in automotive input environments. A 1μA shutdown mode quiescent current (IQ) allows the device to be used in battery-pow.
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 f.
