MPQ4433 Overview
The MPQ4433 is a synchronous, step-down, switching regulator with programmable frequency (350kHz to 2.5MHz) and integrated, internal, high-side and low-side power MOSFETs. The MPQ4433 provides up to 3A of highly efficient output current with current mode control for fast loop response. The wide 3.3V to 36V input range acmodates a variety of step-down applications in automotive input environments.
