MPQ2167A-AEC1

The 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. The MPQ2167A 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.

The MPQ2167A integrates a 35mΩ high-side switch and a 25mΩ synchronous rectifier for high efficiency without an external Schottky diode.

The MPQ2167A can be configured for either advanced asynchronous mode (AAM) or forced continuous conduction mode (FCCM) at light-load. AAM provides high efficiency by reducing switching losses at light load, while FCCM has a controllable frequency and a lower output ripple.

The MPQ2167A offers standard features, including soft start, external SYNC clock, enable control, and a power good indicator. In addition, the MPQ2167A provides over-current protection (OCP) with valley current detection to avoid current runaway, short-circuit protection (SCP), reliable over-voltage protection (OVP), and auto-recovery thermal protection.

With internal compensation, the MPQ2167A requires a minimal number of readily available, standard external components, and is available in a QFN-14 (3mmx3mm) package.
