MPQ2279A-AEC1

6V, Dual 3A/3A, AAM Mode, 2.5MHz, Synchronous Step-Down Converter with Power Good and Soft Start, AEC-Q100 Qualified

详情

The MPQ2279A-AEC1 is a monolithic, dual, step-down, switch-mode converter with built-in internal power MOSFETs. The device achieves 3A/3A of output current (I_OUT) from a 2.5V to 6V input voltage (V_IN) range, with excellent load and line regulation. The output voltage (V_OUT) can be regulated to as low as 0.6V.

Constant-on-time (COT) control provides fast transient response and eases loop stabilization. Fault protections include cycle-by-cycle current limiting and thermal shutdown.

The device is ideal for a wide range of applications, including automotive infotainment systems, clusters, and telematics.

The MPQ2279A-AEC1 requires a minimal number of readily available, standard external components, and is available in a QFN-16 (2.5mmx3.5mm) package. It is AEC-Q100 qualified.
