MPQ4462-AEC1

3.5A, 4MHz, 36V Step-Down Converter

Datasheet

Description

The MPQ4462 is a high-frequency, step-down, switching regulator with an integrated, high-side, high-voltage, power MOSFET. It provides a 3.5A output with current-mode control for fast loop response and easy compensation. The wide 3.8V-to-36V input range accommodates a variety of step-down applications, including those in an automotive input environment. A 120µA operational quiescent current allows for battery-powered applications. Switching-frequency scaling allows for high power-conversion efficiency over a wide load range by scaling down the switching frequency at light loads to reduce the switching and gate driving losses. The frequency foldback prevent inductor-current runaway during startup, and thermal shutdown provides reliable and fault tolerant operation. The MPQ4462 can operate at up to 4MHz for EMI-sensitive applications, such as AM radio and ADSL applications. The MPQ4462 is available in both 3mm×3mm QFN10 and SOIC8E packages.
