The Future of Analog IC Technology
GENERAL 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.
