MPQ2167A is a frequency-configurable (300KHz to 2.2MHz), synchronous step-down converter. It can achieve up to 6A of continuous output current with peak current control for excellent transient response and efficiency performance. It operates from a 2.7V to 6.0V input range and generates an output voltage as low as 0.606V. It is ideal for a wide range of applications including automotive infotainment, clusters and telematics, portable instruments, industrial supplies and battery-powered devices. The MPQ2167A integrates a 35mohm high-side switch and a 25mohm synchronous rectifier for high efficiency without an external schottky diode. In addition, it provides overcurrent protection with valley current detection to avoid current runaway, short-circuit protection, reliable overvoltage protection, and autorecovery thermal protection. With internal compensation, the MPQ2167A requires a minimal number of readily available, standard external components. Available in QFN-14 (3mmx3mm) package.
