MPQ4467GL-AEC1-P

MPQ4467 is a frequency-programmable (350KHz to 2.5MHz), asynchronous, step-down switching regulator with an integrated internal high-side power MOSFET. It provides up to 2.5A of highly efficient output current with current mode control for fast loop response. The wide 3.3V to 36V input range accommodates a variety of step-down applications in automotive input environments, and is ideal for battery powered applications due to its extremely low quiescent current. The MPQ4467 employs AAM (advanced asynchronous modulation) mode, which helps achieve high efficiency in light-load conditions by scaling down the switching frequency to reduce the switching and gate driver losses. Overcurrent protection (OCP) is employed to prevent inductor current runaway. Thermal shutdown provides reliable, fault-tolerant operation. Typical applications includes automotive systems and industrial power systems. Available in a QFN-16 (3mmx4mm) package.
