Description
The MPQ2167 is a frequency programmable (300kHz to 2.2MHz) synchronous step-down converter.It can achieve up to 4A continuous output current with peak current control for excellent transient response and efficiency performance.The MPQ2167 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, telematics, and portable instruments.
The MPQ2167 integrates a 35mΩ high-side switch and a 25mΩ synchronous rectifier for high efficiency without an external Schottky diode.With internal compensation, the MPQ2167 requires a minimum number of readily available standard external components and is available in a QFN-11(2mm x 3mm) package.
The MPQ2167 can be configured for either advanced asynchronous mode (AAM) or forced continuous conduction mode (FCCM) operation at light load.AAM provides high efficiency by reducing switching losses at light load while FCCM has controllable frequency and a lower output ripple.
The MPQ2167 offers standard features, including soft-start, enable control, and a power good indicator.In addition, the MPQ2167 provides over-current protection with valley current detection, which is used to avoid current runaway.Also, it has short-circuit protection, reliable over-voltage protection, and auto recovery thermal protection.
