Product Detail

The MP4433 is a frequency-programmable (350kHz to 2.5MHz), synchronous, step-down, switching regulator with integrated, internal, high-side and low-side power MOSFETs. It 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 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 MP4433 employs advanced asynchronous mode (AAM), which helps to achieve high efficiency in light-load condition by scaling down the switching frequency to reduce switching and gate driving losses. Standard features include soft start (SS), external clock synchronization, enable (EN) control, and power good (PG) indication. High-duty cycle and low dropout mode are provided for automotive cold-crank condition. Over-current protection (OCP) with valley-current detection is employed to prevent the inductor current from running away. Hiccup mode reduces the average current in short-circuit condition greatly. Thermal shutdown provides reliable and fault-tolerant operation. The MP4433 is available in a QFN-16 (3mmx4mm) package.
