Description

The MPQ4560 is a high-frequency, step-down,switching regulator with an integrated, highside, high-voltage, power MOSFET. It provides a 2A output with current mode control for fast loop response and easy compensation. The wide 3.8V-to-55V input range accommodates a variety of step-down applications, including those in automotive input environment. A 12µA shutdown mode supplycurrent 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.
