| The Future of Analog IC Technology The MPQ2560 is a high frequency step-down switching regulator with an integrated internal high-side high voltage power MOSFET. It provides 2.5A output with current mode control for fast loop response and easy compensation. The wide 4.5V to 42V input range accommodates a variety of step-down applications, including those in an automotive input environment. A 12uA shutdown mode quiescent current allows 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 condition to reduce the switching and gate driving losses. The frequency foldback helps prevent inductor current runaway during startup and thermal shutdown provides reliable, fault tolerant operation. By switching at 4MHz, the MPQ2560 is able to prevent EMI Electromagnetic Interference noise problems, such as those found in AM radio and ADSL applications. The MPQ2560 is available in small 3mm x 3mm QFN10 and thermally enhanced SOIC8 packages.

The maximum allowable continuous power dissipation at any ambient temperature is calculated by PD MAX = TJ Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. Internal thermal shutdown circuitry protects the device from permanent damage. 3 The device is not guaranteed to function outside of its operating conditions. 4 Measured on JESD51-7 4-layer board. 11/19/2009 MPS Proprietary Information.
