MPQ4468 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 3.5A 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 MPQ4468 employs AAM mode, which helps achieve high efficiency in light-load condition by scaling down the switching frequency to reduce switching and gate driving losses. Overcurrent protection is employed to prevent the inductor current from running away. Hiccup mode greatly reduces the average current in short-circuit condition. Thermal shutdown provides reliable, fault-tolerant operation. Typical applications include automotive and industrial power systems. The MPQ4468 is available in a QFN-16 (3mmx4mm) package.
