MPQ2124GD-AEC1-Z

MPQ2124 is a frequency-programmable (300KHz to 2.2MHz), synchronous step-down converter. It can achieve up to 3A of continuous output current using peak current control, with excellent transient response and efficiency performance. The MPQ2124 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, as well as portable instruments, industrial supplies and battery powered devices. The MPQ2124 integrates a 35mohm high-side switch and a 25mohm synchronous rectifier for high efficiency without an external schottky diode. The MPQ2124 can be configured for either advanced asynchronous mode (AAM) or forced continuous conduction mode (FCCM) operation at light load. With internal compensation, the MPQ2124 requires a minimal number of readily available, standard external components. Available in QFN-11 (2mmx3mm) package.
