The Future of Analog IC Technology
EV0060 (MP1567)
1.2A, 6V, 800KHz Synchronous Rectified
Step-Down Converter
EVALUATION BOARD
GENERAL DESCRIPTION
The EV0060 is an evaluation board for the
MP1567, 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
QFN package provide a solution requiring a
minimum of space.
