MP1567中文资料1.2A,6V,Synchronous Rectified,Step-Down Converter数据手册MPS规格书

描述 Description

The MP1567 is a 1.2A, 800KHz DC to DC converter designed for low voltage applications requiring high efficiency. Capable of providing output voltages as low as 0.9V from a 3.3V supply voltage, the MP1567 eliminates the need for a 5V rail, providing over 90% efficiency via synchronous rectification and eliminating heat issues in confined spaces. Soft-start operation protects internal circuitry from hard turn on issues. Switching at 800KHz reduces the size of external components and thereby reduces board space. The MP1567 includes cycle-by-cycle current limiting and under voltage lockout. Internal power switches combined with the tiny 10-pin MSOP or QFN packages provide a solution requiring a minimum of space.
