MPQ4569GQ
DESCRIPTION The MPQ4569 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 acmodates a variety of step-down applications in automotive environment. A 5μA shutdown mode quiescent current in full temperature range 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. The MPQ4569 is available in QFN-10 (3mmx3mm) and SOIC-8 EP packages. FEATURES - 20μA Quiescent Current (Active mode) - Wide 4.5V to 75V Operating Input Range - 1.2Ω/0.45Ω Internal Power MOSFETs - Programmable Soft-Start - FB-Tolerance: 1% at...
