MPQ2167 6V, 4A, Frequency Programmable Buck Converter AEC-Q100 Qualified DESCRIPTION FEATURES The MPQ2167 is a frequency programmable 2.7V to 6.0V Operating Input Range (300kHz to 2.2MHz) synchronous step-down Adjustable Output from 0.606V converter. It can achieve up to 4A continuous Up to 4A Continuous Output current output current with peak current control for High Efficiency Synchronous Mode Control excellent transient response and efficiency 35m and 25m Internal Power MOSFET performance. The MPQ2167 operates from a Programmable Frequency up to 2.2MHz 2.7V to 6.0V input range and generates an 42 A Quiescent Current output voltage as low as 0.606V. It is ideal for a Low Shutdown Mode Current wide range of applications, including automotive 100% Duty Cycle Operation infotainment, clusters, telematics, and portable Internal Compensation Mode instruments. Selectable AAM or FCCM Operation Option The MPQ2167 integrates a 35m high-side External Soft Start switch and a 25m synchronous rectifier for Remote EN Control high efficiency without an external Schottky Power Good Indicator diode. With internal compensation, the Cycle-by-Cycle Over-Current Protection MPQ2167 requires a minimum number of readily Short-Circuit Protection available standard external components and is V Under-Voltage Lockout IN available in a QFN-11(2mm x 3mm) package. V Over-Voltage Protection OUT The MPQ2167 can be configured for either Thermal Shutdown advanced asynchronous mode (AAM) or forced Available in QFN-11(2mm x 3mm) Package continuous conduction mode (FCCM) operation Available in AEC-Q100 Grade-1 at light load. AAM provides high efficiency by reducing switching losses at light load while APPLICATIONS FCCM has controllable frequency and a lower Automotive Infotainment output ripple. Automotive Clusters The MPQ2167 offers standard features, including Automotive Telematics soft-start, enable control, and a power good Industrial Supplies indicator. In addition, the MPQ2167 provides Battery-Powered Devices over-current protection with valley current All MPS parts are lead-free, halogen free, and adhere to the RoHS detection, which is used to avoid current runaway. directive.
