OPERATION
The
MP5424
provides
a
complete
power
management solution for 5V systems, such as
televisions. It integrates four high-frequency,
synchronous rectification, step-down switch-
mode converters, as well as three low-dropout
(LDO) regulators and one load switch. The
compact
QFN-26
(3.5mmx4.5mm)
package
reduces component count and PCB space.
The default output voltage (VOUT), start-up
sequence, and dynamic voltage scaling can be
adjusted
via
the
I2C
and
multiple-time
programmable (MTP) interfaces. The I2C also
provides powerful logic functions. See the I2C
Register Map section on page 35 for more
details.
