Monolithic Power Systems MPQ4436
The MPQ4436/4436A is a frequency programmable, synchronous, step-down switching regulator with integrated internal highside and low-side power MOSFETs. It provides 6A (or less) of highly efficient output, with current mode control for fast loop response. The wide 3.3V to 45V input range accommodates a variety of step-down applications in an automotive input environment.| Part No. | MPQ4436 |

DESCRIPTION
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 gate driving losses. An open-drain power good signal indicates that the output is within 93% to 106% of its nominal voltage. Frequency foldback helps prevent inductor current runaway during start-up. Thermal shutdown provides reliable, fault-tolerant operation. High-duty cycle and low dropout mode are provided for the automotive cold crank condition. The MPQ4436/4436A is available in a QFN-20 (4mmx4mm) package. MPQ4436/4436A 45V, 6A, Low IQ, Synchronous Step-Down Converter, AEC-Q100 QualifiedFEATURES
