The Future of Analog IC Technology DESCRIPTION The MP4569 is a step-down switching regulator with integrated high-side/low-side, high-voltage power MOSFETs. It provides a highly efficient output of up to 0.3A. The wide 4.5V to 75V input range accommodates a variety of step-down applications in automotive environment. A 3.5μA shutdown mode quiescent current is good for battery-powered applications. It allows for high power conversion efficiency over a wide load range by scaling down the switching frequency under light-load condition to reduce the switching and gate driver losses. The switching frequency during start-up and short circuit also can be scaled down to prevent inductor current runaway. Thermal shutdown provides reliable, fault-tolerant operation.
