Description

The MPQ4560 is a high frequency step-down switching regulator with integrated internal high-side high voltage power MOSFET. It provides 2A output with current mode control for fast loop response and easy compensation. The wide 4.5V-to-55V input range accommodates a variety of step-down applications, including those in automotive input environment. A 12µA shutdown mode supply current allows use in battery-powered applications. High-power conversion efficiency over a wide load range is achieved by scaling down the switching frequency in light load conditions to reduce the switching and gate driving losses. Frequency foldback prevents inductor current runaway during startup and thermal shutdown provides reliable, fault tolerant operation. By switching at 2MHz, the MPQ4560 can prevent electromagnetic interference problems, such as those found in AM radio and ADSL applications. The MPQ4560 is available in small 3mm x 3mm QFN10 and SOIC8 with exposed pad packages. These MPQ parts target Automotive system and Industrial power system applications.
