The MPQ4568 is a high-frequency, step-down, switching regulator with integrated highside/low-side, high-voltage power MOSFETs. It provides a highly efficient output of up to 100mA. 60V rated MOSFETs and 4.5V to 45V operation range accommodates a variety of step-down applications in automotive input environment. A 5µA shutdown mode quiescent current allows use in 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 helps prevent inductor current runaway. Thermal shutdown provides reliable, fault-tolerant operation. The MPQ4568 is available in a 3mmx3mm QFN10 package.
