MPQ2167GD-Z

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 3ma high-side switch and a 25mohm synchronous rectifier for high efficiency without an external Schottky diode. It can be configured for either AAM or 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 detecting.
