MPQ2167BGDE-AEC1-Z

MPQ2167B is a synchronous step-down converter that achieves up to 4A of continuous output current with peak current control for excellent transient response and efficiency performance. The device operates from 2.7V to 6.0V input range, generates an output voltage as low as 0.606V and has a configurable frequency (300KHz to 2.2MHz). It is ideal for a wide range of applications, including automotive infotainment, clusters, telematics, portable instruments, industrial supplies and battery-powered devices. The device integrates a 35mohm high-side MOSFET and a 25mohm synchronous rectifier for high efficiency without an external schottky diode. AAM provides high efficiency by reducing switching losses while FCCM has a controllable frequency and lower output ripple. With internal compensation, the MPQ2167B requires a minimal number of readily available, standard external components. Available in a QFN-11 (2mmx3mm) package.
