General Description

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 accommodates a variety of step-down applications in automotive input environments.

Overview

The Future of Analog IC Technology.

Key Features

include soft start, external clock synchronization, enable control, and power good indication. High-duty cycle and low dropout mode are provided for automotive coldcrank. Over-current protection (OCP) with valleycurrent detection is employed to prevent the inductor current from running away. Hiccup mode reduces the average current greatly in short-circuit condition. Thermal shutdown provides reliable and fault-tolerant operation. The MPQ4433 is available in a QFN-16 (3mmx4mm) package. MPQ4433 3.
