Monolithic Power Systems’ MP4560 is a high-frequency step-down switching regulator with integrated internal high side high-voltage power MOSFET. It provides 2 A output with current mode control for fast loop response and easy compensation. The wide 4,5 V to 55 V input range accommodates a variety of step-down applications, including those in automotive input environments. A 12 μA shutdown mode quiescent current enables use in battery-powered applications.
High power conversion efficiency over a wide load range is achieved by scaling down the switching frequency at light load conditions to reduce the switching and gate driving losses. Frequency foldback helps prevent inductor current runaway during startup and thermal shutdown provides reliable, fault tolerant operation. By switching at 2 MHz, the MP4560 is able to prevent EMI problems, such as those found in AM radio and ADSL applications. The device is available in small 3 x 3 mm 10-pin QFN and SOIC8 packages with exposed pads.
