Product Detail

The MPQ4561 is a high-frequency, step-down, switching regulator with an integrated internal high-side high voltage power MOSFET. It provides up to a 1.5A 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 12? shutdown mode supply current makes it suitable for battery-powered applications.? A scaled-down switching frequency in light-load conditions provides high power-conversion efficiency over a wide load range while reducing switching and gate driver losses.? The frequency foldback prevents inductor current runaway during startup and thermal shutdown provides reliable, fault tolerant operation. By switching at 2MHz, the MPQ4561 is able to prevent EMI (Electromagnetic Interference) noise problems, such as those found in AM radio and ADSL applications.?The MPQ4561 is available in a 3mm x 3mm QFN10 package with an exposed pad.?These MPQ parts target Automotive system and Industrial power system applications.
