Description
.
The MPQ4436/4436A is a frequency programmable, synchronous, step-down switching regulator with integrated internal highside and low-side power MOSFETs.
Features
* Wide 3.3V to 45V Operating Voltage Range
* 6A Continuous Output Current
* 1.7μA Low Shutdown Supply Current
* 18μA Sleep Mode Quiescent Current
* Internal 48mΩ High-Side and 20mΩ Low-

Switching Frequency f
Applications
* in an automotive input environment. A 1.7μA shutdown mode quiescent current allows the part to be used 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 gat
