MPQ9841 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a very compact solution that achieves 1A of continuous output current with excellent load and line regulation over a wide 3.3V to 36V input supply range. The switching frequency can be programmed or synchronized to an external clock in the range of 350KHz to 2.5MHz. The synchronous operation and ultralow 14µA sleep mode quiescent current provide high efficiency over the output current load range, allowing the MPQ9841 to be used in a variety of step-down applications in automotive input environments and battery-powered applications. Peak-current-mode operation provides fast transient response and eases loop stabilization. The excellent low dropout performance allows the MPQ9841 to be used in high duty cycle applications. The MPQ9841 is available in a space-saving QFN-16 (3mmx4mm) package. Typically used in automotive and industrial power system.
