MPQ2123 is a configurable frequency (300KHz to 2.2MHz), synchronous step-down converter. It can achieve up to 2A of continuous output current with peak current control for excellent transient response and efficiency. It operates from a 2.7V to 6V input voltage range and can generate an output voltage as low as 0.606V. MPQ2123 is ideal for a wide range of applications, including automotive infotainment systems, clusters, telematics, industrial supplies, battery-powered devices and portable instruments. It integrates a 40mohm high-side MOSFET (HS-FET) and a 30mohm synchronous rectifier for high efficiency without an external schottky diode. MPQ2123 can be configured to operate in advanced asynchronous modulation (AAM) mode or forced continuous conduction mode (FCCM) under light-load conditions. AAM provides high efficiency by reducing switching losses at light load, while FCCM offers controllable frequency and a lower output ripple. It is available in a QFN-11 (2mmx3mm) package.
