MP1567 Datasheet PDF - Monolithic Power Systems

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.
