MP4560DQ
MP4560DQ is 55V Step-Down Converter manufactured by Monolithic Power Systems.
DESCRIPTION
The MP4560 is a high frequency step-down switching regulator with integrated internal highside high voltage power MOSFET. It provides 2A output with current mode control for fast loop response and easy pensation.
The wide 3.8V to 55V input range acmodates a variety of step-down applications, including those in automotive input environment. A 12µA shutdown mode supply current allows use in battery-powered applications.
High power conversion efficiency over a wide load range is achieved by scaling down the switching frequency at light load condition to reduce the switching and gate driving losses.
The frequency foldback helps prevent inductor current runaway during startup and thermal shutdown provides reliable, fault tolerant operation.
By switching at 2MHz, the MP4560 is able to prevent EMI (Electromagnetic Interference) noise problems, such as those found in AM radio and ADSL applications.
The MP4560 is available in small 3mm x 3mm 10-pin QFN and SOIC8 with exposed pad packages.
